 - 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。
