 1. Open the repo in VS Code/Cursor and use **Dev Containers: Reopen in Container** (or Codespaces).
 2. `pnpm install` runs automatically. Env vars for qr-api are set in `devcontainer.json` (`DB_PATH`, `UPLOADS_PATH`, `KUTT_API_KEY`, `QR_API_URL`) so you can run qr-api and qr-web without a `.env` file.
 3. In the container, start the apps:
-   - **qr-api:** `pnpm --filter qr-api dev` (listens on 8080)
-   - **qr-web:** `pnpm --filter qr-web dev` (listens on 3000)

+    - **qr-web:** `pnpm --filter qr-web dev` (listens on 3000)
 4. Open the forwarded ports (3000 = qr-web, 8080 = qr-api). Data and uploads are stored under `.data/` in the repo (gitignored).
 5. For full stack (Kutt + qr-api + qr-web in Docker), run `docker compose up` from the **host** (or from inside the container if Docker-in-Docker is enabled). Set `DB_PASSWORD`, `JWT_SECRET`, and optionally `KUTT_API_KEY` in `.env` for that.
