 该拆分只改变 `api-server` 文件组织，不改变 `/api/runtime/puzzle/*` route、DTO、error envelope、SpacetimeDB schema、公开 gallery cache 语义或计费语义；后续继续细分时也必须先保持行为不变，再单独讨论领域规则下沉。
 
+`/api/runtime/puzzle/runs*` 当前接受 `RuntimePrincipal`，可同时识别登录用户 Bearer 和 runtime guest token。推荐页嵌入运行态的正式开局、交换、拖拽、下一关、暂停、道具与排行榜请求，应由前端在登录态下继续携带账号 access token；匿名游客仅在确认为未登录时走 runtime guest token。不要再把拼图 runtime 当成只认普通 Bearer 的纯账号接口。

 抓大鹅 Match3D `api-server` 内部拆分：
 
 - `server-rs/crates/api-server/src/modules/match3d.rs` 继续负责路由装配和 body limit；对外 handler 名称保持不变。

 - 结果页单关测试只能把完整草稿持久化，并通过 `levelId` 指定运行态起始关卡；不得把单关快照作为整份草稿调用 `updatePuzzleWork`，否则 source session 和作品 profile 的 `levels` 会被覆盖成单关，退出重进后其它关卡会丢失。
 - 结果页生成关卡图时若关卡名为空，前端必须传 `shouldAutoNameLevel=true`，后端复用首关命名契约先按画面描述生成关卡名，再在图片生成后用视觉命名结果精修，并把生成名和 UI 背景提示词随本次关卡快照写回。
 - 拼图运行态背景优先读取当前关卡 `levelBackgroundImageSrc/levelBackgroundImageObjectKey`，旧数据才兼容 `uiBackgroundImageSrc/uiBackgroundImageObjectKey`；本地试玩、直达指定关卡和正式 `next-level` 推进时，目标关卡缺关卡背景时必须继承同作品首个可用关卡背景，仍缺失时才沿用当前运行态快照背景或默认 UI。运行态按钮视觉优先读取当前关卡 `uiSpritesheetImageSrc/uiSpritesheetImageObjectKey`，先按透明 alpha 自动边界检测识别 spritesheet 中的独立按钮展示矩形，再按原图位置从左到右、从上到下映射到返回、设置、下一关、提示、原图、冻结；同一组件还要按较高 alpha 阈值派生紧致点击热区，透明留白和柔边低 alpha 区域尽量不响应点击。检测失败时回退旧固定六格裁切，缺失时才用现有图标按钮兜底。有 spritesheet 时，返回和设置按钮的点击容器只提供透明点击区，不再叠加默认白色圆形底；底部提示、原图、冻结三枚素材按检测矩形的原始宽高比显示，不能强行拉伸成正圆或铺满整列。底部道具区不再使用连片胶囊背景，提示、原图、冻结三个按钮均匀分布；运行态只展示按钮素材本身，不额外叠加“提示 / 原图 / 冻结”文字。
+- 推荐页本身不是登录门禁入口，未登录用户点击底部或侧边栏的推荐 Tab 应直接进入嵌入运行态，不主动打开登录弹窗。推荐页嵌入运行态必须按真实身份分流：已登录用户或本地已有 access token 时，启动拼图和后续排行榜 / 下一关等正式请求继续走账号 Bearer；只有确认为匿名访客时才申请并透传 runtime guest token。`/api/runtime/puzzle/runs*` 后端统一接受 `RuntimePrincipal`，可识别账号用户和匿名 runtime guest；推荐卡片的后台读写请求仍使用 local auth impact，避免单卡 401 清空整站登录态。创作、个人作品、删除、发布、Remix 等账号或所有权动作仍保持普通用户鉴权。
 - 拼图运行态棋盘不叠加分块蒙版、描边、阴影、选中底色或合并块 SVG 轮廓；拼图片本体需要裁切为圆角形状，单块使用独立圆角裁切，合并块使用 SVG 原生 `clipPath` 裁切整体外轮廓，外凸角和内凹角分别计算半径，内凹角半径要比外凸角更明显以避免手机 WebView 中看起来仍是直角。原图道具只在用户主动确认后打开独立原图查看层，不在当前拼图棋盘上叠加原图。
 - 拼图运行态拖拽必须完全跟随手指或鼠标位置，`pointermove` 期间即时写入可见拼块的 transform，不依赖等待后端回包、React 重渲染或下一帧动画队列；进入拖动后不展示拼块选中态或“已选择”提示，松手后再提交目标格同步规则真相。
 - 拼图运行态的提示、设置等点击弹层跟随当前运行态主色主题，使用普通圆角主题面板，不复用像素九宫格素材框。
