ZipZop Pro Studio — production-ready stack + Kinetic Caption Engine (prototype)

This update includes:

• Postgres-backed auth and JWT tokens.
• Background processing with BullMQ & Redis and a Worker for FFmpeg tasks.
• Kinetic Caption Engine (ASS generation, preview, burn).
• Demo Premium system (upgrade endpoint — demo only, no payment provider).
• Client (Vite + React) with a simple editor to preview and generate kinetic captions.
• Dockerfile + docker-compose.yml (images include ffmpeg and fonts).

Quick start (local):

1. Copy .env.example to .env and set JWT_SECRET and DB/Redis values.
2. npm install
3. cd client && npm install
4. mkdir -p data/tmp data/processed
5. docker-compose up --build

Notes:

• Replace demo premium flow with a proper payments integration (Stripe) for production.
• Use S3 or persistent storage for uploads & processed files in production.# Zipzop-pro
