 - 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。
+- 决策：`PlatformToolModalShell` 继续承接 RPG 结果页发布检查弹窗；`RpgCreationResultActionBar.tsx` 只保留发布检查、封面预览、封面设置和发布动作语义，不再直接维护 `createPortal`、平台主题 overlay、白底 remap panel、header close、body/footer spacing 和遮罩关闭逻辑。后续结果页 / 工具页里同形态的白底 portal 弹窗优先迁移到 `PlatformToolModalShell`；编辑器大壳、暗色 runtime overlay 和需要专属布局的面板继续保留局部 shell。
 - 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。
