 - Chunked uploads are enabled by default. Uses setting `CHUNKED_UPLOADS_ENABLED=true`.
 - Configure chunk size with `CHUNK_SIZE_MB` (default: `50`). The client only uses chunked mode for files larger than this.

 ### How it works
 
 1. **Queue** - Files selected in the browser are queued; each gets a client-side ID.
-2. **De-dupe (local)** - Server computes **SHA‑1** and checks `state.db`. If seen, marks as **duplicate**.
 3. **Save** - The file is saved to the local filesystem under `./data/uploads`.
 4. **Album** - If an album is specified via an invite link, or a folder name is provided on the public page, the file is saved into a corresponding subdirectory. Client-side folder structure is also preserved.
 5. **Progress** - Backend streams progress via WebSocket to the same session.
