+
+### 改进
+
+- README 精简为产品宣传页，详细说明指向文档站
+- 双域名文档补充：未知 Host 风险、Cloudflare 橙云部署、勿用 Pages/Workers 整站反代
+- 文档截图更新（登录页等）；旧 `docs/*.md` 长文迁入 `docs-site/`
+
+## [1.2.0] - 2026-08-28
+
+### 变更
+
+- 图片统一存放在 `data/images/`；遗留 `blog/`、`twikoo/` 等并列目录需迁移后升级

+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+

+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:

+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General

+## Overview
+
+PicHost is a media management platform for NAS devices, home servers, and small self-hosted deployments. It manages images, videos, and general-purpose files in one place, with multi-user access, tags, search, multiple storage backends, HLS video processing, full-site backup and restore, backend migration, and site-to-site synchronization.
+
+The first visit opens a web setup wizard. Administrators can either create an account or restore an existing `.phost.tar.gz` backup.

+### Images
 
-## Quick Start
+- Upload by drag and drop, file picker, or `Ctrl+V` paste, with configurable formats, size limits, batch limits, and rate limits.
+- Server-side Sharp-based WebP compression, with optional original preservation and optional browser-side WebP compression.
+- Search, pagination, storage/source/tag filters, grid or list layouts, detail views, multiple link formats, bulk tagging, and bulk deletion.
+- Media counts and source statistics, Referer hotlink protection, and configurable referrer allowlists.
 
-### Docker (recommended)
+### Video and HLS
+
+- Dedicated video upload and library pages for MP4, M4V, WebM, MOV, MKV, AVI, FLV, WMV, MPG, and MPEG.
+- Automatic thumbnail generation and optional asynchronous HLS transcoding.
+- `copy`, `veryfast`, `medium`, `slow`, and `compress` presets, with configurable concurrency, CPU thread count, and target bitrate.
+- Transcode progress and failure reporting, with automatic cleanup of the source, thumbnail, playlist, and HLS segments.
+- Original, thumbnail, and HLS links, plus MP4 remux download for HLS videos.
+
+### File Hosting
+
+- A dedicated file library with uploads, search, pagination, tags, bulk deletion, direct links, and download links.
+- Configurable file-bed access policy, with separate domains supported for images, videos, and files.
+
+### Users and Access Control
+
+- Administrator and standard-user accounts; standard users only see and manage their own media.
+- Slider, Cloudflare Turnstile, and Cap verification, with optional public registration.
+- Profile and password management, administrator password reset, and account-system migration.
+- Per-user tags and automatic deletion policies.
+- Login and upload rate limits, global and personal API tokens, and activity logs.
+
+### Storage
+
+- Local disk, S3-compatible object storage, and Telegram channels or groups.
+- S3-compatible support includes R2, COS, OSS, AWS S3, and similar services, with `proxy` or `public` access modes.
+- Multiple backends, configurable default and enabled states, and per-backend capacity quotas.
+- Migration of images, videos, files, and indexes between configured backends, with an optional target backend switch after migration.
+
+### Backup and Synchronization
+
+- Complete `.phost.tar.gz` site backups containing the database, images, videos, files, thumbnails, HLS content, and tags.
+- Restore previews for file count, media size, new files, conflicts, and skip/overwrite conflict handling.
+- Streaming uploads for large backups without loading the complete archive into memory.
+- Restore directly from the first-run setup page; cloud storage secrets are excluded and must be re-entered after restore.
+- Push or pull synchronization between two PicHost sites, for all media or only images, videos, or files.
+- Resume support, conflict policies, and job progress; matching usernames must already exist on both sites.
+
+### API and Compatibility
+
+- APIs for images, videos, files, tags, search, bulk operations, backups, and system information.
+- Global and personal tokens, accepted through request headers or upload forms.
+- Twikoo / EasyImage-compatible uploads through `POST /api/index.php`.
+- Built-in API documentation and debugger with generated `curl` examples.

+## Deployment
+
+### Docker
 
 ```bash
 docker run -d \
@@ -63,147 +119,97 @@ docker run -d \
   -p 6892:6892 \
   -v ./data:/data \
   --restart unless-stopped \
-  muxui/pichost:latest
+  yeomaiyelove/pichost:latest
 ```
 
-Default port: **6892**. Open `http://<host>:6892` in your browser and complete the setup wizard.
+Open `http://<host>:6892` and complete the setup wizard. Data is stored in the host `./data` directory by default.
 
-**Forgot password** (requires `docker exec` / server access):
+Docker Hub:
+
+- `yeomaiyelove/pichost:latest`
+- `yeomaiyelove/pichost:<version>`
+
+### Windows
+
+The Windows x64 installer is self-contained:
+
+- Node.js and FFmpeg are bundled; no runtime download is required on the target computer.
+- The first launch opens the web setup wizard.
+- Data is stored in the `data` directory under the installation directory.
+- Uninstall asks whether to delete the data directory. If preserved, the database, media, and backups remain on disk.
+
+### FnOS
+
+FnOS uses a dedicated x86 FPK package that runs the bundled Docker image:
+
+1. Import the matching `yeomaiyelove/pichost:<version>` image into FnOS Docker.
+2. Confirm that the image appears locally.
+3. Install the FPK and choose account creation or backup restore in the wizard.
+
+The FPK uses the local image and does not pull PicHost from the internet.
+
+## Development and Packaging
+
+### Local Development
 
 ```bash
-docker exec pichost reset-password              # admin only, when there is exactly one
-docker exec pichost reset-password <username>   # admin or regular user
-```
-
-A random password is printed. Fails if the user does not exist.
-
-If you cloned the repo, you can also use `docker compose up -d` (see `docker-compose.yml`).
-
-### Local development
-
-```bash
-npm install
-cp .env.example .env   # optional
+npm ci
 npm run dev
 ```
 
-Open `http://localhost:3000/setup` to create the admin account. Data defaults to `./data`.
+The first visit opens `/setup`. Common verification commands:
 
-### Legacy migration
+```bash
+npm test
+npm run typecheck
+npm run lint
+npm run build
+```
 
-If you only had `ADMIN_SECRET` and no user table, log in with the secret once and follow the migration wizard.
+### Release Artifacts
+
+```bash
+npm run pack:docker
+npm run pack:fpk
+npm run pack:windows
+```
+
+On Windows, all artifacts can be built at once:
+
+```bash
+npm run pack:all
+```
+
+Output directories:
+
+- Docker image archive: `dist-docker/`
+- FnOS package: `dist-fpk/`
+- Windows installer: `dist-windows/release/`
+
+See [packaging/README.md](packaging/README.md) for requirements and override options.
+
+## Data Directory
+
+- Docker uses `/data` by default and supports the `DATA_DIR` override.
+- Windows installs use the `data` directory under the installation path.
+- Local development uses `data` in the project root.
+
+The database is stored as `pichost.db`. Create regular full-site backups and keep the `.phost.tar.gz` files on separate storage.

-## 快速开始
+## 核心功能
 
-### Docker（推荐）
+### 图片管理
+
+- 支持拖拽、文件选择和 `Ctrl+V` 粘贴上传，可配置格式、大小、批量数量和频率限制。
+- 服务端使用 Sharp 压缩为 WebP，也可保留原图；支持可选的浏览器端 WebP 压缩。
+- 图库支持搜索、分页、存储后端/上传来源/标签筛选，以及网格和列表视图。
+- 支持查看详情、复制多种链接格式、批量打标和批量删除，并提供媒体数量与来源统计。
+- 支持 Referer 防盗链和来源域名白名单。
+
+### 视频库与 HLS
+
+- 独立的视频上传、搜索和管理页面，支持 MP4、M4V、WebM、MOV、MKV、AVI、FLV、WMV、MPG、MPEG 等格式。
+- 上传后自动生成视频缩略图，并可根据设置异步转码为 HLS。
+- 支持 `copy`、`veryfast`、`medium`、`slow`、`compress` 等转码档位，可限制并发数、CPU 核心数和目标码率。
+- 管理转码进度与失败原因，支持删除时同步清理原视频、缩略图、播放列表和 HLS 分片。
+- 支持复制原视频、缩略图和 HLS 地址，并可将 HLS 视频重新封装下载为 MP4。
+
+### 文件床
+
+- 独立管理普通文件，提供上传、搜索、分页、标签、批量删除和直链/下载链接。
+- 文件床访问策略可在后台配置，文件、图片和视频可分别使用独立域名。
+
+### 多用户与权限
+
+- 管理员与普通用户账号体系，普通用户只能查看和管理自己的媒体。
+- 支持滑块、Cloudflare Turnstile 和 Cap 人机验证，可选择开放注册。
+- 支持修改资料、修改密码、管理员清空密码和迁移到账号密码登录。
+- 每个用户拥有独立标签和自动删除策略，可设置媒体保存天数。
+- 提供登录与上传频率限制、全局/个人 API Token 和操作日志。
+
+### 存储与迁移
+
+- 支持本地磁盘、S3 兼容对象存储和 Telegram 频道/群组。
+- S3 兼容 R2、COS、OSS、AWS S3 等服务，支持 `proxy` 和 `public` 两种访问方式。
+- 可配置多个存储后端、默认后端、启用状态和容量配额。
+- 支持在已配置后端之间迁移图片、视频、文件和索引，迁移后可将目标后端设为默认。
+
+### 备份与站点同步
+
+- 创建和恢复完整 `.phost.tar.gz` 站点备份，包含数据库、图片、视频、文件、缩略图、HLS 内容和标签。
+- 备份恢复前可预检文件数量、媒体大小、新增与冲突情况，并选择跳过或覆盖冲突。
+- 支持大体积备份流式上传，无需将整个压缩包读入内存。
+- 未初始化时可在首次设置页直接恢复备份；云存储密钥不会写入备份，恢复后需重新填写。
+- 支持两站点双向同步，可推送或拉取全部媒体，也可只同步图片、视频或文件。
+- 站点同步支持断点继续、冲突策略和任务进度；目标站点需要预先存在同名用户。
+
+### API 与兼容性
+
+- 提供图片、视频、文件、标签、搜索、批量操作、备份和系统接口。
+- 支持全局 Token 和个人 Token，可通过请求头或表单上传。
+- 兼容 Twikoo / EasyImage 的 `POST /api/index.php` 上传接口。
+- 前端内置 API 文档和调试界面，支持直接生成并复制 `curl` 示例。
+
+## 部署方式
+
+### Docker
 
 ```bash
 docker run -d \
@@ -63,152 +120,97 @@ docker run -d \
   -p 6892:6892 \
   -v ./data:/data \
   --restart unless-stopped \
-  muxui/pichost:latest
+  yeomaiyelove/pichost:latest
 ```
 
-默认端口 **6892**。浏览器打开 `http://<主机IP>:6892`，按引导创建管理员即可。
+浏览器打开 `http://<主机IP>:6892`，按向导创建管理员即可。数据默认保存在宿主机的 `./data` 目录。
 
-**忘记密码**（需能执行 `docker exec`，相当于服务器权限）：
+Docker Hub：
 
-```bash
-# 无参数：重置管理员（仅当系统中只有一个管理员时）
-docker exec pichost reset-password
+- `yeomaiyelove/pichost:latest`
+- `yeomaiyelove/pichost:<版本号>`
 
-# 指定用户名：可重置管理员或普通用户
-docker exec pichost reset-password 用户名
-```
+### Windows
 
-终端会打印随机新密码；用户不存在时会报错。登录后请到「修改密码」更换。
+项目提供 Windows x64 一体安装包：
 
-本地：`npm run reset-password` 或 `npm run reset-password -- 用户名`
+- 内置 Node.js 和 FFmpeg，不依赖目标电脑预装运行环境。
+- 首次启动后按 Web 向导完成设置。
+- 数据保存在安装目录下的 `data` 子目录。
+- 卸载时会询问是否删除数据；选择保留后，数据库、图片、视频和备份不会被删除。
 
-已克隆仓库时也可用 `docker compose up -d`（见仓库内 `docker-compose.yml`）。
+### 飞牛 NAS
+
+飞牛使用独立的 x86 FPK 安装包，FPK 以内置 Docker 镜像方式运行：
+
+1. 在飞牛 Docker 中导入与 FPK 版本对应的镜像包。
+2. 确认镜像列表中存在 `yeomaiyelove/pichost:<版本号>`。
+3. 安装 FPK，并按向导选择创建管理员或从备份恢复。
+
+FPK 使用本地镜像，不会自动联网拉取 PicHost 镜像。
+
+## 开发与打包
 
 ### 本地开发
 
 ```bash
-npm install
-cp .env.example .env   # 可选
+npm ci
 npm run dev
 ```
 
-访问 `http://localhost:3000/setup` 创建管理员；数据目录默认 `./data`。
+默认开发地址由 Nuxt 输出，首次访问会进入 `/setup`。常用检查命令：
 
-### 遗留部署迁移
+```bash
+npm test
+npm run typecheck
+npm run lint
+npm run build
+```
 
-若旧版仅配置了 `ADMIN_SECRET`、尚无用户表，可用密钥登录一次，Web 引导迁移为账号密码。
+### 构建安装产物
+
+```bash
+npm run pack:docker
+npm run pack:fpk
+npm run pack:windows
+```
+
+Windows 环境可以一次构建全部产物：
+
+```bash
+npm run pack:all
+```
+
+输出位置：
+
+- Docker 离线镜像：`dist-docker/`
+- 飞牛安装包：`dist-fpk/`
+- Windows 安装程序：`dist-windows/release/`
+
+详细环境要求和可覆盖参数见 [打包说明](packaging/README.md)。
+
+## 数据目录
+
+- Docker 默认使用 `/data`，通过 `DATA_DIR` 可覆盖。
+- Windows 安装版使用安装目录下的 `data`。
+- 本地开发默认使用项目根目录下的 `data`。
+
+数据库文件为 `pichost.db`。建议定期在后台创建整站备份，并将 `.phost.tar.gz` 文件保存到其他磁盘。
