 - 2026-06-11 追加：`PlatformAsyncStatePanel` 继续补齐 RPG 首页分类分支；移动端“发现 -> 分类”、桌面发现页“分类”和桌面首页“作品分类”模块现在都统一委托共享状态壳切换外层 `loading / empty / content`，分类控制条与排序按钮继续留在内容 slot 中。筛选后无结果的“当前筛选下没有作品。”也统一改成内层 `PlatformAsyncStatePanel` 切换，不再在三处 JSX 中各自维护嵌套 ternary。
 - 2026-06-11 追加：`PlatformDarkModalFooter` 不只收动作按钮区，也继续覆盖纯内容 footer；`CompanionCampModal.tsx` 底部“营地气氛”区域已改成 `layout="content"` + `padding="roomy"` 的共享 footer frame，保留原有文案和卡片布局，不再单独手写 `border-t border-white/10 px-5 py-4`。
 - 2026-06-11 追加：`PlatformDarkModalFooter` 继续从标准双按钮 footer 扩到 detail / confirm 收尾；`NpcModals.tsx` 的交易详情 footer 和 `MapModal.tsx` 的场景切换确认 footer 已改成复用同一个 dark footer frame，即使只有单个“关闭”按钮也不再手写 `flex justify-end`。这条抽象继续只覆盖 dark / pixel modal 里的底部分隔线与常规动作区排布，不向白底 profile 弹窗 footer、sticky 工作台 footer 或运行态 HUD 工具条扩张。
+- 2026-06-11 追加：`PlatformFilterToolbar.tsx` 作为薄结构组件收口 RPG 首页分类工具条；组件只承接“筛选按钮 + tabs + 排序按钮”的排布与 `mobile / desktop` 两种布局差异，不持有筛选状态、空态或排序逻辑。后续只有在同构壳层真的复现时才继续往 `common` 扩覆盖面；如果只是单页内局部重复、接口会越抽越胖，就优先退回文件内 helper。
+- 2026-06-11 追加：`SquareImageCropModal.tsx` 的白底弹窗壳层改为复用 `UnifiedModal.tsx`，同时给 `UnifiedModal` 薄补 `titleId` 与 `closeIcon` 透传，让裁剪弹窗继续保留自定义 close icon、无 backdrop / Escape 关闭和两列 footer，而不把 `PlatformProfileModalShell` 这类带页面语义的壳层倒灌回 `common/`。这条规则适用于 `common` 级工具弹窗：先看 `UnifiedModal` 能不能承接，再决定是否需要新的薄壳。
 - 2026-06-11 追加：`PlatformProfileModalShell` 继续补齐标准 footer 插槽，直接透传 `UnifiedModal.footer` 与 `footerClassName`；`RpgEntryHomeView.tsx` 的昵称修改弹窗已改成标准 profile footer，不再把双按钮动作区手写在 body 末尾。后续个人中心里同类“表单内容 + 底部双按钮”弹窗优先走壳层 footer 接法。
 - 2026-06-11 追加：`PlatformProfileModalShell` 的标准 footer 接法继续扩展到单 CTA 表单收尾；`PlatformProfileRewardCodeRedeemModal.tsx` 的兑换按钮已迁到壳层 footer，body 只保留输入和反馈消息。`PlatformAsyncStatePanel` 同日继续扩展到 `PlatformAssetPickerGrid`、`VisualNovelSavePanel.tsx` 与 `AccountModal.tsx` 的账号安全三个子区块；其中公共素材网格继续把 `error` banner 放在状态壳外层，保持错误提示可与加载态或内容并存的原语义。
 - 2026-06-11 追加：按钮层继续补齐轻量漏网项。`PlatformTagEditor.tsx` 的标签 chip 删除入口已改成紧凑 `PlatformIconButton`，保留透明背景和原 chip 高度；`RpgEntryCharacterSelectView.tsx` 的两处“返回”按钮统一沉到局部 `CharacterSelectBackButton`，底层委托 `PlatformActionButton surface="editorDark"`。同日 `GenerationProgressHero.tsx` 新增 `GenerationHeaderBackButton`，`CustomWorldGenerationView.tsx` 与 `BarkBattleGeneratingView.tsx` 已开始复用这套暖色生成页返回入口骨架；后续同类轻量返回按钮与 chip 删除按钮优先继续沿共享按钮 + 薄包装的方向推进。

 19.3.45. 白底 / 浅色结果页与工作台顶部的轻量返回入口继续收口到 `src/components/common/PlatformBackActionButton.tsx`；该 Module 固定承接 `PlatformActionButton tone="ghost" size="xs"` 上的 `ArrowLeft + 返回文案` 骨架，并只暴露 `compact / regular` 两档尺寸，分别覆盖紧凑结果页 header 与标准白底结果页顶栏。当前 `PuzzleResultView.tsx`、`SquareHoleResultView.tsx`、`Match3DResultView.tsx`、`VisualNovelResultView.tsx` 四个结果页已接入 `variant="compact"`，`PuzzleClearResultView.tsx`、`JumpHopResultView.tsx`、`WoodenFishResultView.tsx` 三个结果页已接入 `variant="regular"`，`BabyObjectMatchResultView.tsx` 继续使用紧凑款并保留 `className="px-3"` 贴合原横向留白。暖色生成页顶部返回入口继续走 `GenerationHeaderBackButton`，`BigFishResultView.tsx` 这类 dark hero / 强品牌 special case 继续保留 `PlatformIconButton variant="darkMini"` 路线，不强行并入同一个白底返回按钮基元。后续白底结果页、浅色工作台或普通 platform 顶栏里若只是“左箭头 + 返回”轻量返回入口，优先直接复用 `PlatformBackActionButton`，只在局部补尺寸和少量外边距，不再各页重复手写 ghost button class。
 19.3.46. `PlatformNavigableListItem` 继续从桌面 flat row 扩展到首页公开列表里的排行行与分类行；`RpgEntryHomeView.tsx` 的 `PlatformRankingItem` 和 `PlatformCategoryGameItem` 现在都统一委托共享 `button + leading + body + trailing` 骨架，同时保留原有 `platform-ranking-item__*`、`platform-category-game-item__*` 局部 class 承接封面尺寸、标题摘要、公开 badge、metric 和右侧 `试玩 / 进入` affordance。后续首页、发现页或 profile 侧同类“封面 + 文本主体 + 右侧动作提示”的浅色导航行，优先先尝试复用 `PlatformNavigableListItem` 并把局部视觉挂在业务 class 上，不要为了这类 row 再回退成原生 `<button>` 手写布局；但教培 promo card、runtime 列表项和带复杂手势的卡片仍保留本地语义，不把共享行骨架扩成万能作品卡。验证命令：`npx vitest run src/components/rpg-entry/RpgEntryHomeView.recharge.test.tsx`、`npm run typecheck`、`npm run check:encoding`、`git diff --check`。
 19.3.47. `PlatformDarkModalFooter` 继续从标准双按钮 footer 扩展到 detail / confirm 收尾：`NpcModals.tsx` 的交易详情单按钮 footer 与 `MapModal.tsx` 的场景切换确认 footer 已接入共享 dark footer frame，分别保留“关闭”单 CTA 和“取消 / 确认前往”双 CTA 的业务语义、按钮 tone 与禁用态。后续 dark / pixel modal 里若只是标准底部分隔线 + 常规动作区排布，优先直接复用 `PlatformDarkModalFooter`，即使只有单个按钮也不再手写 `flex justify-end`；但像 `SquareImageCropModal.tsx` 这类白底弹窗 footer、sticky 工作台 footer 和运行态 HUD 工具条继续留在各自语义壳层，不强行混到 dark footer 抽象里。验证命令：`npx vitest run src/components/NpcModals.test.tsx src/components/MapModal.test.tsx`、`npm run typecheck`、`npm run check:encoding`、`git diff --check`。
+19.3.48. `RpgEntryHomeView.tsx` 里的分类筛选工具条继续从页面内重复 JSX 收口到 `src/components/common/PlatformFilterToolbar.tsx`；该 Module 只承接“筛选按钮 + 横向 tabs + 排序按钮”的结构排布，暴露 `mobile / desktop` 两种 layout 以覆盖移动端 divider + 独立排序行和桌面端同排布局差异，但不持有分类列表、筛选状态、空态或排序逻辑。当前 RPG 首页分类区已接入，后续若其它白底列表页也出现同构的筛选壳层，可直接复用这套薄结构组件；若场景只是在单页内局部重复、接口会为了兼容业务差异不断膨胀，则优先退回文件内 helper，不把 `common` 扩成假的“万能筛选条”。验证命令：`npx vitest run src/components/common/PlatformFilterToolbar.test.tsx src/components/rpg-entry/RpgEntryHomeView.recharge.test.tsx`、`npm run typecheck`、`npm run check:encoding`、`git diff --check`。
+19.3.49. `SquareImageCropModal.tsx` 的白底 modal 壳层与 footer 已收口到 `src/components/common/UnifiedModal.tsx`；`UnifiedModal` 为此只薄补了 `titleId` 与 `closeIcon` 透传，继续由调用方决定 `closeOnBackdrop`、`closeOnEscape`、`portal`、header/footer 样式和按钮内容，不额外掺入 profile 业务语义，也不让 `common/` 反向依赖 `platform-entry/`。`SquareImageCropModal.tsx` 继续保留裁剪拖拽、pointer capture、保存禁用态与两列等宽 footer 行为，只把 header / body / footer 外壳交给共享 modal 承接。后续 `common` 级白底工具弹窗若只是标准标题栏 + 内容区 + footer 按钮排布，优先先看 `UnifiedModal` 是否够用，再决定是否需要新的薄壳；不要为了一个弹窗把 `PlatformProfileModalShell` 之类带页面语义的壳层倒灌回 `common`。验证命令：`npx vitest run src/components/common/SquareImageCropModal.test.tsx src/components/common/UnifiedModal.test.tsx src/components/unified-creation/workspaces/PuzzleCreationWorkspace.interaction.test.tsx src/components/rpg-entry/RpgEntryHomeView.recharge.test.tsx`、`npm run typecheck`、`npm run check:encoding`、`git diff --check`。
 19.3. creative-agent 首页的侧边栏菜单、账号入口、开启新对话、我的创作、首页激励 CTA 和 prompt suggestion 按钮迁移到 `PlatformIconButton` / `PlatformActionButton`；首页继续保留 `creative-agent-home__*` 本地 class 承接透明顶栏、抽屉和品牌化胶囊视觉，不把视觉回收和语义收口绑成一次大改。`Beta` 徽标和历史记录纯文本行暂保留本地实现，等出现更多同构轻量列表行后再评估是否抽新的共享 row primitive。
 19.4. 大鱼吃小鱼结果页 hero 的返回入口迁移到 `PlatformIconButton variant="darkMini"`，测试 / 发布动作迁移到 `PlatformActionButton surface="editorDark"`；结果页只保留测试运行、发布提交和文案状态语义，不再手写 hero 顶栏按钮壳。
 19.4.1. 大鱼吃小鱼结果页的发布失败弹层迁移到 `src/components/common/PlatformStatusDialog.tsx`；`PlatformStatusDialog` 补充自定义图标、可访问标签和动作按钮样式透传后，`BigFishResultView` 不再保留 `BigFishResultErrorModal` 内联的 `UnifiedConfirmDialog + PlatformIconBadge` 组合。结果页只保留失败文案和关闭回调，发布失败的状态图标、遮罩、白底面板和“知道了”主动作统一由共享状态弹层承接。验证命令：`npm run test -- src/components/common/PlatformStatusDialog.test.tsx src/components/big-fish-result/BigFishResultView.test.tsx`、`npm run typecheck`。
