在线字体子集化与 WOFF2 生成器
把上传的 TTF/OTF 按指定字符集做子集化，并输出 WOFF2/WOFF/TTF 及配套 CSS，面向网页加载优化与多语言站点。
英文 Prompt:
You are to build a production-ready web app: "Font Subsetter + Webfont Exporter".
Scope:
- Upload a TTF/OTF font.
- Input a character set (paste text) and/or choose presets (Latin, CJK, Emoji excluded).
- Generate a subset font and export: WOFF2 + WOFF + TTF.
- Generate CSS @font-face snippet and a preview page that renders sample text.
- Show before/after size, glyph count, and a downloadable ZIP.
Tech constraints:
- Frontend: Next.js 14 (App Router) + Type + Tailwind.
- Backend: Node.js API (Next route handler). Font processing must run server-side.
- Use a reliable font subsetting approach (e.g., Python fonttools in a container OR a Node-compatible library). Prefer a Docker-free, cross-platform solution; if native deps are required, document them clearly.
- Security: validate file type, size limits, no SSRF, no external network calls.
Deliverables (must output all):
1) Full project file tree.
2) Complete source code for every file.
3) Local run commands (dev + production build).
4) Deployment guide (Docker optional; include a non-Docker path).
5) At least 8 QA checks / test cases covering edge cases (invalid fonts, huge fonts, empty charset, CJK, etc.).
UX:
- Steps: upload -> set charset -> process -> download.
- Provide clear error messages and progress indicator.
