Can I vibecode Sejda Web?

Build a comprehensive personal replacement for Sejda Web, focusing on providing a clean, powerful web-based PDF manipulation suite, entirely hosted locally. Your goal is to build a high-quality PDF tool that replicates the core capabilities of Sejda Web in a secure, private, and intuitive environment.

Technology Stack:
- Frontend: Next.js 15, TypeScript, Tailwind CSS, and a modern component library (like Shadcn UI) for a polished, responsive user interface. Use a robust PDF rendering library (like react-pdf) to display document previews.
- Backend: Python 3.12, FastAPI, for a fast and type-safe API.
- Document Processing: Use `pikepdf` for general PDF manipulation (merging, splitting, rotating, watermarking), and LibreOffice headless for Office-to-PDF conversions. Integrate Tesseract OCR for Optical Character Recognition.
- Database: PostgreSQL for logging events and metadata.

Core Features & Operations:
The core loop involves uploading a PDF, configuring an operation via the UI, processing on the backend, and downloading the result.
1. PDF Editing & Manipulation: 
   - Merge multiple PDFs into a single document with drag-and-drop reordering.
   - Split PDFs by page range, specific pages, or file size.
   - Organize pages: rotate, delete, or visually reorder pages within a document.
   - Compress PDFs to reduce file size while maintaining acceptable quality.
2. Security & Formatting:
   - Add text or image watermarks with customizable opacity, position, and rotation.
   - Redact sensitive information by overlaying black boxes on specific coordinates.
   - Protect PDFs with passwords (encryption) and remove passwords.
3. Conversion & Advanced Utilities:
   - Convert Office formats to PDF, and convert PDF pages to images.
   - Perform OCR on scanned PDFs to generate searchable text overlays.
   - Basic annotation: allow adding simple text layers or shapes to a PDF page.

Application Architecture & Data Management:
- Ensure the application works locally out of the box with one simple documented setup script.
- Prioritize data privacy: process all files locally and do not implement any telemetry, analytics, or tracking.
- Keep original files immutable. Any operation should yield a new versioned output file stored securely in a local directory.
- Maintain an append-only event log recording timestamps, operations performed, and file hashes for auditability.
- Include a cleanup job to automatically delete temporary files after a configurable expiry period.

User Experience & Polish:
- Provide clear visual feedback: loading spinners, progress bars, success toasts, and readable errors.
- Render accurate page previews for visual operations like splitting or reordering.

Documentation & Exclusions:
- Create a README detailing the architecture, local setup instructions, environment variables, and backup procedures.
- Deliberately exclude: user authentication, billing, enterprise document governance, legally binding electronic signatures, and identity verification. Focus solely on being the best local PDF utility.
Finish by running backend tests for core transformations and providing commands to start the stack.
