feedback2 WE: README, DEPLOY.md (new §6), setup and doctor say what falls back without the local-client art instead of 不影响游戏, and that a server without the client can copy public/assets/local + data/local-assets.json from the same version's bundle; DESIGN §22.5 (#42)

-- **官方 3D 棋盘**需要从本机的《明日方舟》PC 客户端提取贴图（Windows 原生客户端、macOS 的 CrossOver 或 PlayCover）。`npm run setup` 检测到客户端时会询问是否提取（需要 Python 3.8+，依赖装在项目内的 `.venv-extract`，不影响系统）；之后可以用 `node tools/setup.mjs --local` 重新提取，或用 `--game "<…/StreamingAssets/AB/Windows>"` 指定路径。没有客户端时自动使用 2D 棋盘，其他功能不受影响。
+- **本地客户端素材（可选）**：官方 3D 棋盘、部分官方界面图标（交流按钮与表情面板的边框、模组类型图标等）和灼热 / 炽焰源石虫的官方模型需要从本机的《明日方舟》PC 客户端提取（Windows 原生客户端、macOS 的 CrossOver 或 PlayCover）。`npm run setup` 检测到客户端时会询问是否提取（需要 Python 3.8+，依赖装在项目内的 `.venv-extract`，不影响系统）；之后可以用 `node tools/setup.mjs --local` 重新提取，或用 `--game "<…/StreamingAssets/AB/Windows>"` 指定路径。没有客户端时游戏照常运行，这几样换成替代样式：2D 棋盘、样式相近的图标、染色的普通源石虫。表情和「玩法说明」的教程图随上面的素材一起从公开镜像下载，不需要客户端。没有客户端的服务器（例如 Linux VPS）也可以从**同一版本**的整合包里复制 `public/assets/local/` 和 `data/local-assets.json`，见 [docs/DEPLOY.md](docs/DEPLOY.md) 的「本地客户端素材」。
 - 素材下载优先使用 GitHub，失败时自动改用 jsDelivr 镜像。
 - `npm run doctor`（即 `node tools/doctor.mjs`）可以随时诊断：Node 版本、素材是否完整、端口占用、局域网地址和防火墙。

 An **unofficial, non-commercial fan remake** of Arknights' seasonal auto-chess tower-defense mode *Stronghold Protocol: Alliance*, played in the browser: solo, or 1–4 player co-op (AI teammates can fill seats). Combat is simulated in each player's browser, so a low-power PC can host.

 - **Play with friends:** create a co-op room and share the 4-letter key or the `?room=KEY` link. On a LAN, use the address printed at start; otherwise use a virtual-LAN tool, a tunnel or a VPS — see [docs/DEPLOY.md](docs/DEPLOY.md).
