资源组更新缩略图

@@ -7,13 +7,13 @@ Eagle 的离线 Spine 骨骼动画预览插件，支持 Spine 3.4–4.3，适用
 1. 将同一套骨骼文件（`.skel` / `.skel.bytes` / Spine `.json`）、图集（`.atlas` / `.atlas.txt`）和配套贴图一起导入 Eagle，建议放在同一个 Eagle 文件夹内。
 2. 打开骨骼或图集文件即可预览动画，并可切换动画、皮肤、速度、循环、背景和 PMA。
 3. 插件不接管导入阶段的缩略图，由 Eagle 自身处理。
-4. 打开预览后，原有按钮可把当前帧设为当前素材的自定义缩略图。其左侧的“为当前资源组生成缩略图…”会先明确列出受影响的骨骼、atlas 和贴图，得到确认后才批量生成，并始终跳过已有自定义缩略图的素材。
+4. 打开预览后，原有按钮可把当前帧设为当前素材的自定义缩略图。其左侧的“为关联资源生成缩略图”会列出同 stem 的骨骼、atlas 及已验证贴图；骨骼与 atlas 默认勾选，图片和已有自定义缩略图的素材默认不勾选；用户仍可主动选择并覆盖，原图无法由插件自动恢复。
 
 ## 安全与隐私
 
 - Atlas 贴图只允许安全的相对路径；绝对路径、`..`、盘符、UNC、URI 和越界符号链接会被拒绝。
 - 跨素材配对只使用当前 Eagle 素材库中已枚举并验证的文件。
-- 单素材按钮只作用于当前素材。资源组按钮会先列出全部受影响素材并要求确认，且不会覆盖已有自定义缩略图。
