 - 决策：`PlatformAsyncStatePanel` 从 profile modal 扩展到作品架类白底 panel；`CustomWorldCreationHub.tsx` 的作品架主体现在也统一走 `loadingState / emptyState / children` 三段 slot，但 error + 重试继续留在业务层外侧，不把共享组件扩成“banner + retry + content”全能状态机。后续白底作品架或列表 panel 若只是互斥的 `loading / empty / content`，优先直接复用这套骨架。
 - 决策：`CopyFeedbackButton.tsx` 的 `actionSurface` 分支继续收口到 `PlatformActionButton`，`pill` 分支继续保留 `PlatformPillBadge` 风格；复制反馈按钮不再直接调用 `getPlatformActionButtonClassName` 手拼平台按钮基础 chrome。后续同类“复制状态机 + 平台动作按钮”组合优先直接复用 `CopyFeedbackButton`，不要在业务页重新混写图标、文案、aria 和动作按钮 class。
 - 决策：白底 / 暗色面板里的轻量空态和普通 CTA 继续向共享组件收口。`PuzzleResultView.tsx` 的缺草稿提示、`RpgCreationAssetDebugPanel.tsx` 的空诊断提示、`VisualNovelEntityGrid` 的空实体列表、`AccountModal.tsx` 里账号安全分区的“无安全限制 / 无登录设备 / 无操作记录”以及 `LoginScreen.tsx` 的“当前登录入口暂不可用”都改为 `PlatformEmptyState`，`Match3DResultView.tsx` 的引用素材列表直接复用 `PlatformAssetPickerGrid` 自己的空态；`AdventureEntityModal.tsx` 的私聊按钮、`InventoryPanel.tsx` 的锻造 / 合成按钮、`RpgCreationRoleAssetStudioModalImpl.tsx`、`RpgCreationEntityEditorShared.tsx` 里的局部 `ActionButton` 包装层，以及 `RpgAdventurePanel.tsx` / `RpgAdventurePanelOverlays.tsx` 里标准 runtime CTA 都改为委托 `PlatformActionButton surface="editorDark"`。后续白底子面板里的只读空态优先使用 `PlatformEmptyState surface="subpanel"`；暗色编辑 / 运行面板里的普通动作优先使用 `PlatformActionButton surface="editorDark"`，若业务仍需 `stopPropagation`、tone 映射、运行态 icon 排版或局部字号，可保留薄包装层，但不要再直接写原生 `<button>` 基础 chrome。
+- 决策：白底 / 浅色结果页和工作台顶部的“左箭头 + 返回文案”轻量返回入口统一收口到 `src/components/common/PlatformBackActionButton.tsx`；共享组件固定承接 `PlatformActionButton tone="ghost" size="xs"` 上的返回按钮骨架，并只开放 `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。当前已覆盖 `PuzzleResultView.tsx`、`SquareHoleResultView.tsx`、`Match3DResultView.tsx`、`VisualNovelResultView.tsx`、`PuzzleClearResultView.tsx`、`JumpHopResultView.tsx`、`WoodenFishResultView.tsx` 与 `BabyObjectMatchResultView.tsx`；暖色生成页继续走 `GenerationHeaderBackButton`，`BigFishResultView.tsx` 这类 dark hero / 强品牌返回入口继续走 `PlatformIconButton darkMini`，不把三条视觉语义线硬并成一个组件。
 - 决策：`CustomWorldNpcVisualEditor.tsx` 的本地 `ActionButton` 和 `SkillEffectPreview.tsx` 的“重新预览”按钮也继续并入这条暗色按钮收口线，统一委托 `PlatformActionButton surface="editorDark"`；局部包装层只保留 `stopPropagation`、图标排布、`tone` 映射和极少量视觉微调。后续暗色编辑器里的局部动作按钮若只是普通 CTA，不再新增原生 `<button>` 实现，优先沿用“薄包装 + 共享按钮本体”模式。
 - 决策：RPG 创作侧标准 dark header / footer 动作也继续纳入同一条按钮收口线。`RpgCreationRoleAssetStudioModalImpl.tsx` 的 header“关闭”、`RpgCreationEntityEditorShared.tsx` 的 footer“取消”以及 `RpgCreationRoleAssetStudioFooter.tsx` 的“保存到当前角色”都改为委托 `PlatformActionButton surface="editorDark"`；局部壳层只保留布局、宽度/字号贴合和少量 tone 语义，不再为标准 dark close / cancel / save CTA 单独维护原生 `<button>` 基础 chrome。
 - 决策：RPG runtime overlay 里的标准 dark CTA 和可点击 dark row 也继续纳入这条收口线。`RpgAdventurePanelOverlays.tsx` 的 goal panel“知道了”、任务详情里的“领取任务 / 返回交付”、任务完成提示里的“打开任务日志”都改为委托 `PlatformActionButton surface="editorDark"`；设置面板里的“运行统计”入口改为 `PlatformSubpanel as="button" surface="dark"`。像素风 choice button、HUD launcher、奖励物品格和输入 composer 保持 runtime 专属语义，不继续硬并到普通平台按钮。

 19.3.42. `PlatformAsyncStatePanel` 继续从首页扩展到公共素材网格、runtime 面板和账号子区块：`PlatformAssetPickerGrid` 现已统一用共享状态壳承接 `loading / empty / content`，但继续把 `error` banner 留在外层，以保持“错误提示可与内容或加载态并存”的原语义；`VisualNovelSavePanel.tsx` 的存档列表，以及 `AccountModal.tsx` 里的“安全状态 / 当前登录设备 / 账号操作记录”三个子区块也都改成各自使用 `PlatformAsyncStatePanel`。后续白底列表、素材选择器或账号子面板若只是标准互斥异步状态，优先按这三种接法复用共享状态壳，不再把读取态和空态分支手写回组件内部。验证命令：`npx vitest run src/components/common/PlatformAssetPickerCard.test.tsx src/components/visual-novel-runtime/VisualNovelRuntimePanels.emptyState.test.tsx src/components/auth/AccountModal.test.tsx src/components/platform-entry/PlatformProfileRewardCodeRedeemModal.test.tsx`、`npm run typecheck`、`npm run check:encoding`、`git diff --check`。
 19.3.43. 轻量按钮漏网继续向共享按钮收口：`PlatformTagEditor.tsx` 的标签 chip 删除入口已改成紧凑 `PlatformIconButton`，保留 `label="删除标签 ${tag}"`、透明背景和原 chip 高度，不再手写裸 `<button>`；`RpgEntryCharacterSelectView.tsx` 两处重复的“返回”按钮已统一沉到文件内 `CharacterSelectBackButton`，底层委托 `PlatformActionButton surface="editorDark"`，保留原有暗色视觉与文案。后续同类“局部 chip 删除按钮”优先先用 `PlatformIconButton` 压缩尺寸和视觉；暗色轻量返回 / 返回上一级 CTA 则优先用 `PlatformActionButton surface="editorDark"` 包一层局部 helper，不再复制原生 `<button>` class。验证命令：`npx vitest run src/components/common/PlatformTagEditor.test.tsx src/components/rpg-entry/RpgEntryCharacterSelectView.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。
