Move to bench.nagi.fun with simplified URL scheme

- Vite base '/' and root favicon for the custom domain
- Artifact paths normalized to outputs/<model-id>/<case-id>.<ext>
  (pelican SVG renamed); RUNS now derives the path by convention,
  with an optional file override
- Deep links: #<case-id> anchors a case, #<case-id>:<model-id> also
  preselects the model tab; tab clicks replaceState the hash so the
  current view is always shareable
- README documents the URL scheme and the legacy github.io 301s

 ```
-outputs/<model-id>/<artifact>   模型产出原文件（HTML / SVG），按模型分目录
-site/                           展示站点（Vite + React + Tailwind v4 + GSAP，bun 驱动）
-site/src/data/cases.ts          案例定义：双语提示词、模型列表、产出文件映射
-.github/workflows/deploy.yml    GitHub Pages 自动部署
+outputs/<model-id>/<case-id>.<ext>   模型产出原文件（HTML / SVG），文件名 = 案例 id

+## URL 规则 / URL scheme
+
+| URL | 含义 / Meaning |
+| --- | --- |
+| `https://bench.nagi.fun/` | 站点首页 / Home |
+| `https://bench.nagi.fun/#<case-id>` | 定位到某个案例 / Anchor to a case (e.g. `#mythos-craft`) |
+| `https://bench.nagi.fun/#<case-id>:<model-id>` | 定位案例并选中模型 / Case + preselected model tab |
+| `https://bench.nagi.fun/outputs/<model-id>/<case-id>.<ext>` | 产物直链 / Raw artifact |
+
+切换模型标签时地址栏自动更新（`replaceState`），当前视图随时可直接分享。旧域名链接（`https://nagi-studio.github.io/nagi-bench/*`）由 GitHub Pages 自动 301 重定向到 `https://bench.nagi.fun/*`，路径保留。
+
+Switching a model tab updates the address bar in place, so the current view is always shareable. Legacy `nagi-studio.github.io/nagi-bench/*` links are 301-redirected by GitHub Pages to `bench.nagi.fun/*` with the path preserved.

 ## 添加案例或模型 / Adding a case or model
 
-1. 把产出文件放进 `outputs/<model-id>/`。
+1. 把产出文件放进 `outputs/<model-id>/`，命名为 `<case-id>.<ext>`（如 `mythos-craft.html`）。
 2. 在 `site/src/data/cases.ts` 里登记：
    - 新模型：加入 `MODELS`（`status: 'ran' | 'pending'`）。
    - 新案例：加入 `CASES`（中英双语 `title` / `tagline` / `prompt`）。
-   - 产出映射：在 `OUTPUTS` 里把案例 id 对应到模型 id 与文件路径。
+   - 运行记录：在 `RUNS` 里登记案例 id 对应的模型 id（可附双语 `note` 运行备注；文件名不符合约定时用 `file` 覆盖）。
 3. 推送到 `main`，GitHub Actions 自动构建并部署。
 
-Drop the artifact into `outputs/<model-id>/`, register it in `site/src/data/cases.ts` (model in `MODELS`, case in `CASES` with bilingual prompts, file path in `OUTPUTS`), then push to `main` — GitHub Actions deploys automatically.
