在线字体子集化（Subset）与 WOFF2 打包工具
把大体积 TTF/OTF 字体按指定字符集裁剪成更小的子集，并一键输出 WOFF2/CSS/示例页。
英文 Prompt:
You are to generate a complete, runnable web app that subsets font files to reduce size.
Requirements:
- Build a full-stack project with a React UI (Vite) + Node.js API (Express) in a single repo.
- Features:
1) Upload TTF/OTF/WOFF/WOFF2.
2) Choose subset mode: (a) custom characters textarea, (b) range presets (Basic Latin, CJK common), (c) auto-detect from pasted text.
3) Produce subset output formats: WOFF2 + WOFF + TTF (as available).
4) Generate @font-face CSS and an HTML preview page.
5) Show before/after file sizes and glyph counts.
- Implementation guidance:
- Use fontkit (or similar) for parsing and subsetting; if a toolchain is needed, include it in the repo.
- Validate inputs; reject non-font files.
- Handle large uploads (up to 30MB) with streaming and size limits.
- Store jobs in a temp folder and clean up automatically.
- Deliverables:
- A clear file tree.
- Full source code for UI and API.
- `npm install` / `npm run dev` commands.
- Production build and deployment notes (Docker + a simple reverse proxy config).
- Tests: at least 5 checks (unit or integration) OR a QA checklist covering edge cases.
- Provide sample fonts as download s only (do not embed copyrighted font binaries).
