 - 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。
 - 决策：NPC dark modal footer 和暗色明细空态也继续纳入同一条收口线。`NpcModals.tsx` 里的交易 / 赠礼 / 招募弹窗 footer 按钮和物品详情“关闭”按钮都改为委托 `PlatformActionButton surface="editorDark"`，交易右侧“请选择一件物品”提示改为 `PlatformEmptyState surface="editorDark"`；`CharacterInfoShared.tsx` 的 `BuildContributionDetailPanel` 空明细也改为 `PlatformEmptyState surface="editorDark"`。数量 stepper、赠礼 / 招募 option card、标签强度按钮这类带独立业务语义的控件继续保留局部实现。
+- 决策：详情页头部动作组合统一收口到 `src/components/common/PlatformDetailTopbar.tsx` 与 `src/components/common/PlatformDetailShareActions.tsx`。`PlatformDetailTopbar` 只负责返回按钮、标题居中槽位和右侧动作槽位的布局，可在 `pill` / `icon` 返回入口之间切换；`PlatformDetailShareActions` 只负责“前置 badge 区块 + 作品号复制 + 分享复制”这组稳定动作，并允许按页面关闭复制或分享其中一项。`RpgEntryWorldDetailView.tsx` 已接入 overlay 版完整动作组，`PlatformWorkDetailView.tsx` 已接入 icon topbar 与 solid 版作品号复制动作，同时继续保留公开详情页自己的顶部 icon 分享入口和分享反馈提示。后续详情页若只是复用返回、标题、作品号复制或分享动作排列，优先组合这两个薄组件，不把作者、摘要、封面、轮播或业务 CTA 塞进共享配置对象。

 19.3.32. 标准平台 modal header 的关闭入口继续统一到 `PlatformModalCloseButton variant="platformIcon"`；`PuzzleResultView.tsx` 的关卡详情 / 发布弹窗、`RpgCreationResultActionBar.tsx` 的发布检查弹窗，以及 `PuzzleHistoryAssetPickerDialog.tsx` 的历史素材弹窗已迁移。像素风 runtime、drawer collapse、玩法规则面板和运行态专属 overlay 继续保留本地 close 语义，不把 `PlatformModalCloseButton` 硬塞进非平台 modal header 场景。
 19.3.33. `PlatformAsyncStatePanel` 从 profile modal 扩展到作品架：`CustomWorldCreationHub.tsx` 的作品架主体现在也统一通过 `loadingState / emptyState / children` 三个 slot 切换，保留外层 error + 重试提示不并入共享状态骨架。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 `PlatformAsyncStatePanel`，不要再在业务 JSX 中重复拼 skeleton 和“当前筛选下没有内容”的分支。验证命令：`npx vitest run src/components/custom-world-home/CustomWorldCreationHub.test.tsx src/components/custom-world-home/CustomWorldCreationHub.interaction.test.tsx`、`npm run check:encoding`。
 19.3.34. `CopyFeedbackButton.tsx` 的 `actionSurface` 分支继续向共享按钮收口：带平台动作外观的复制按钮现在直接组合 `PlatformActionButton`，仅保留 `pill` 分支继续复用 `PlatformPillBadge` 风格。复制反馈按钮不再手动调用 `getPlatformActionButtonClassName` 拼平台按钮基础 chrome；后续同类“复制状态机 + 平台动作按钮”组合也优先走 `CopyFeedbackButton + PlatformActionButton`，不要在业务页或按钮组件里重新混写图标、文案、aria 和 class。验证命令：`npm run test -- src/components/common/CopyFeedbackButton.test.tsx src/components/common/PlatformActionButton.test.tsx`。
+19.3.35. 详情页头部动作组合收口到 `src/components/common/PlatformDetailTopbar.tsx` 与 `src/components/common/PlatformDetailShareActions.tsx`；前者只承接“返回 / 标题 / 右侧动作槽位”的 topbar 骨架，并允许 `pill` / `icon` 两种返回按钮语义，后者只承接“前置 badge 区块 + 作品号复制 + 分享复制”这一组稳定动作，不吸收详情页自己的标题、摘要、作者、封面轮播或业务 CTA。`RpgEntryWorldDetailView.tsx` 已接入完整的 overlay 版动作组合，统一世界主题 badge、作者、发布时间、作品号和分享入口；`PlatformWorkDetailView.tsx` 已接入 icon topbar 与 solid 版作品号复制动作，并继续保留公开详情页自己的顶部 icon 分享入口和分享反馈提示。后续同类详情页若只是复用返回按钮骨架、标题居中布局或作品号 / 分享动作排列，优先直接组合这两个 Module，不要把整页 detail header 抽成巨型配置对象。验证命令：`npx vitest run src/components/common/PlatformDetailTopbar.test.tsx src/components/common/PlatformDetailShareActions.test.tsx src/components/rpg-entry/RpgEntryWorldDetailView.test.tsx src/components/platform-entry/PlatformWorkDetailView.test.tsx`、`npm run typecheck`、`npm run check:encoding`、`git diff --check -- src/components/common/PlatformDetailTopbar.tsx src/components/common/PlatformDetailTopbar.test.tsx src/components/common/PlatformDetailShareActions.tsx src/components/common/PlatformDetailShareActions.test.tsx src/components/rpg-entry/RpgEntryWorldDetailView.tsx src/components/platform-entry/PlatformWorkDetailView.tsx`。
 19.3.35. 白底 / 暗色面板里的轻量空态和普通 CTA 继续按共享组件收口：`PuzzleResultView.tsx` 的“还没有可编辑的拼图草稿”、`RpgCreationAssetDebugPanel.tsx` 的“没有可诊断项”、`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交给 `PlatformAssetPickerGrid` 自己处理空态。`AdventureEntityModal.tsx` 的私聊按钮、`InventoryPanel.tsx` 的锻造 / 合成按钮、`RpgAdventurePanel.tsx` 底部 `队伍 / 背包 / 换一换 / 退出聊天` 按钮，以及 `RpgAdventurePanelOverlays.tsx` 里的“查看任务 / 保存并退出”都改为 `PlatformActionButton surface="editorDark"`，业务页只贴回局部 sky / emerald / runtime 皮肤。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"`，若还需要 stopPropagation、局部字号或图标排版，可保留薄包装层，但不要再回退到原生 `<button>` 基础 chrome。验证命令：`npm run test -- src/components/puzzle-result/PuzzleResultView.test.tsx src/components/rpg-creation-result/RpgCreationAssetDebugPanel.test.tsx src/components/AdventureEntityModal.test.tsx src/components/InventoryPanel.test.tsx src/components/auth/AccountModal.test.tsx src/components/rpg-runtime-panels/RpgAdventurePanel.test.tsx src/components/rpg-runtime-panels/RpgAdventurePanel.npcChat.test.tsx src/components/rpg-runtime-panels/RpgAdventurePanel.questOffer.test.tsx src/components/common/PlatformEmptyState.test.tsx src/components/common/PlatformActionButton.test.tsx`、`npm run check:encoding`。
 19.3.36. `VisualNovelEntityGrid` 的空态也继续收口到 `PlatformEmptyState surface="subpanel" size="inline"`；角色 / 场景 / 剧情阶段共用这一网格组件后，白底实体列表里的“暂无角色 / 暂无场景 / 暂无剧情阶段”等同构空态不再回退成 `PlatformSubpanel`。同时，`RpgCreationRoleAssetStudioModalImpl.tsx` 与 `RpgCreationEntityEditorShared.tsx` 保留局部 `ActionButton` 语义壳，但按钮本体已统一委托给 `PlatformActionButton surface="editorDark"`，只在包装层补最小的 `stopPropagation`、tone 映射和局部 class 适配。后续类似“暗色编辑器局部包装按钮”优先沿用这种薄包装模式，不再直接手写原生 `<button>` 基础 chrome。验证命令：`npm run test -- src/components/visual-novel-result/VisualNovelResultView.test.tsx src/components/common/PlatformEmptyState.test.tsx src/components/rpg-creation-asset-studio/RpgCreationRoleAssetStudioModal.test.tsx src/components/CustomWorldEntityEditorModal.test.tsx src/components/common/PlatformActionButton.test.tsx`、`npm run check:encoding`。
 19.3.37. 暗色编辑器里的局部动作按钮继续往共享 `editorDark` button 收口：`CustomWorldNpcVisualEditor.tsx` 的本地 `ActionButton` 和 `SkillEffectPreview.tsx` 的“重新预览”按钮都改为委托 `PlatformActionButton surface="editorDark"`。这类局部包装仍可保留 `stopPropagation`、图标布局、`tone` 映射和少量局部视觉覆写，但按钮本体不再直接使用原生 `<button>` 承接边框 / 底色 / hover / disabled chrome。验证命令：`npm run test -- src/components/common/PlatformActionButton.test.tsx`、`npm run typecheck`、`npm run check:encoding`、`git diff --check`。
