+### 🔑 Invite Passwords (New)
+- When creating an invite, you can optionally set a password.
+- Recipients must enter the password before they can upload through the link.
+- The app stores only a salted hash server‑side; sessions that pass the check are marked authorized.
+
+### 🧩 Chunked Uploads (New)
+- Opt‑in support for splitting large files into chunks to bypass proxy limits (e.g., Cloudflare 100MB).
+- Enable with `CHUNKED_UPLOADS_ENABLED=true`; tune `CHUNK_SIZE_MB` (default 95MB).
+- The frontend automatically switches to chunked mode only for files larger than the configured chunk size.
+
+### 📱 Device‑Flexible HMI (New)
+- Fully responsive UI with improved spacing and wrapping for small and large screens.
+- Mobile‑safe file picker and a sticky bottom “Choose files” bar on phones.
+- Safe‑area padding for devices with notches; refined dark/light theme behavior.
+- Desktop keeps the dropzone clickable; touch devices avoid accidental double‑open.
+
+### ♻️ Reliability & Quality of Life (New)
+- Retry button to re‑attempt any failed upload without re‑selecting the file.
+- Progress and status updates are more resilient to late/reordered WebSocket events.
+- Invites can be created without an album, keeping uploads unassigned when preferred.
+
+### Last 8 Days – Highlights
+- Added chunked uploads with configurable chunk size.
+- Added optional passwords for invite links with in‑UI unlock prompt.
+- Responsive HMI overhaul: mobile‑safe picker, sticky mobile action bar, safe‑area support.
+- Retry for failed uploads and improved progress handling.
+- Support for invites with no album association.

 ### 🌙 Dark Mode
 - Automatically detects system dark/light preference on first visit
 - Manual toggle button in the header (sun/moon icon)

+## Chunked Uploads
+
+- Enable chunked uploads by setting `CHUNKED_UPLOADS_ENABLED=true`.
+- Configure chunk size with `CHUNK_SIZE_MB` (default: `95`). The client only uses chunked mode for files larger than this.
+- Intended to bypass upstream limits (e.g., 100MB) while preserving duplicate checks, EXIF timestamps, album add, and per‑item progress via WebSocket.
