Initial commit: Shelfless – alternative Audiobookshelf frontend

React + Vite + TypeScript SPA covering the full ABS feature set (library
browsing, item detail, metadata/cover editing, podcasts, player with session
sync, admin: users/libraries/scanner/server settings). Dev uses a dynamic
CORS proxy; production is served by server/index.mjs (static + reverse proxy
to ABS_URL). Includes systemd unit and installer under deploy/.

+# Deployment (Proxmox LXC, auto-start)
+
+Shelfless runs as a small Node server that serves the built SPA **and** reverse-proxies
+the ABS API. So the browser only ever talks to Shelfless (one origin → no CORS), and the
+Audiobookshelf address is fixed by the deployment (`ABS_URL`) — users only log in.
+
+## 1. Prerequisites on the container
+```bash
+apt update && apt install -y nodejs npm git   # Node 18+ (20+ recommended)
+node --version
+```
+
+## 2. Get the code & build
+```bash
+mkdir -p /opt/shelfless && cd /opt/shelfless
+# copy the project here (git clone / scp / rsync), then:
+npm ci
+npm run build        # produces dist/
+```
+
+## 3. Configure the ABS target
+The server reads these env vars (see the systemd unit):
+- `ABS_URL` — the Audiobookshelf server, e.g. `http://127.0.0.1:13378` (same container)
+  or `http://192.168.1.71:13378` (another host).
+- `PORT` — the port Shelfless listens on (default `8080`).
+- `HOST` — bind address (default `0.0.0.0`).
+
+Quick manual test:
+```bash
+ABS_URL=http://127.0.0.1:13378 PORT=8080 npm start
+# open http://<container-ip>:8080
+```
+
+## 4. Auto-start with systemd
+```bash
+cp deploy/shelfless.service /etc/systemd/system/shelfless.service
+# edit WorkingDirectory / ABS_URL / PORT inside the file if needed
+systemctl daemon-reload
+systemctl enable --now shelfless
+systemctl status shelfless        # check it's running
+journalctl -u shelfless -f        # logs
+```
+
+Open `http://<container-ip>:8080`. The setup screen asks only for username + password
+(the server URL is fixed). "Angemeldet bleiben" keeps you logged in across reloads;
+otherwise you log in each session.
+
+## Updating
+```bash
+cd /opt/shelfless
+git pull            # or copy new files
+npm ci && npm run build
+systemctl restart shelfless
+```
+
+## Notes
+- Put it behind a reverse proxy (nginx/Caddy/Traefik) for HTTPS + a domain if you expose
+  it beyond the LAN.
+- Proxied paths: `/api`, `/login`, `/logout`, `/public`, `/status`, `/hls`, `/feed`,
+  `/socket.io`. Everything else is served from `dist/` (SPA fallback to `index.html`).
