英文 Prompt:
You are a senior full-stack engineer. Build a production-ready web app: "Online PDF Form Filler". Requirements: - Users upload a fillable PDF (AcroForm). - Server extracts form fields (name, type, default value, options, required if available) and returns JSON. - UI renders an editable field list and a PDF preview; user edits values and clicks "Export". - Exported PDF preserves original pages, fills the form values, and embeds a small audit footer (timestamp + masked session id). - Do NOT call external paid APIs. Tech stack (must follow): - Next.js (App Router) + Type - Node.js API routes - PDF library: pdf-lib - UI: Tailwind CSS Deliverables (must include all): 1) Complete source code. 2) File tree. 3) Local run commands (pnpm preferred) and a Dockerfile. 4) Deployment notes for Vercel and a self-hosted Node server. 5) Security checklist (upload limits, MIME sniffing, path traversal, SSRF avoidance). 6) Tests: at least 5 test cases (unit or integration). Include a QA checklist if some tests are manual. Output format: - Start with file tree. - Then provide the code for each file in separate fenced blocks. - End with run/deploy/test instructions.中文释义:
