 3. Build with the project's npm script before previewing. The playable entry is the package directory's `dist/index.html`; never report an unbuilt bare-module page as playable. Import assets or configure public assets so all runtime media is included in dist; preview and exports cannot read outside it.
 4. Build a complete playable loop: visible objective, responsive input, meaningful state changes, success or failure feedback, and a reliable restart path where the game needs one.
 5. Fit the active game scene to desktop and mobile viewports without accidental page scrollbars. Reserve deliberate safe space for HUD elements instead of covering interactive content.
+   - **画布居中只能由一处负责。** 使用 `Phaser.Scale.FIT` 与 `autoCenter: Phaser.Scale.CENTER_BOTH` 时，canvas 的直接父容器应使用尺寸明确的普通块布局，不再对同一 canvas 叠加 Grid/Flex 居中、`place-items: center`、自动外边距或居中 transform。Phaser 自动计算的 margin 与 CSS 居中叠加会使竖屏画面向右偏移。
+   - 若决定由 CSS 居中，则显式使用 `autoCenter: Phaser.Scale.NO_CENTER`，由 CSS 独立完成定位；外围页面可以继续使用 Grid/Flex，限制只针对同一 canvas 的重复定位。
+   - 出现偏移先检查游戏自身的 CSS 与 Phaser scale 配置，不添加 AGC 预览容器固定偏移补偿。修改布局后重新构建 dist，在桌面、移动及窗口 resize 后检查 canvas 相对游戏父容器居中（误差不超过 1 CSS px）、画面完整且无意外滚动条；不能仅凭 build 成功宣称布局通过。
 6. Invoke `taonier-art-assets` for every new game brief that needs visual assets. First reuse suitable registered Taonier art; when the brief's required visual elements are missing or unsuitable, call the reviewed `agc_tools` generation/edit workflow in the same task. After the tool returns, wire its relative paths into the game and verify the rendered result. A game with unused generated assets or placeholder emoji/CSS where requested art should appear is not complete. Load media defensively only for genuinely optional effects, and never relabel a local placeholder as platform art.
 7. Let Phaser own the render loop and input dispatch. Avoid duplicate scenes, stale event listeners, and state that survives restart unintentionally.
 8. After a meaningful game change, use the browser playtest Skill and fix issues shown by real evidence before reporting completion.
