+# CANCOM Simple Signage — Agent Guide
+
+## Start
+
+```bash
+pip install -r requirements.txt
+python app.py
+docker compose up -d
+```
+
+`python app.py` serves on `http://localhost:5005`. `app.py` runs Flask with `debug=True`, `host="0.0.0.0"`, and `port=5005`.
+
+## Source Of Truth
+
+- Single Flask app in `app.py`; there is no database.
+- Persistent state is `config.json` plus files under `media/<screen>/`.
+- `README.md` is stale on the port number; trust `app.py`.
+- Existing repo instructions in this file are the main local guidance; there is no `opencode.json` or workflow config in this repo.
+
+## Behavior To Preserve
+
+- `GET /player/<screen>` renders the playlist and auto-reloads from `/playlist/<screen>/hash`.
+- `GET /admin` requires login; `config.json.admin` holds the credentials.
+- URL playlist items are stored as dicts like `{"url": "https://...", "zoom": 0.8}` and the zoom value must survive save/reorder flows.
+- `.html` items in `media/` are rendered inline as content, not in an iframe.
+- `config.priority.enabled` makes the priority playlist show on every screen.
+- `POST /api/customer` generates `welcome.html` and inserts it at the front of the lobby playlist.
+
+## Repo Quirks
+
+- `media/` and media file extensions are gitignored.
+- The app has no configured tests, lint, typecheck, formatter, or CI.
+- Hardcoded secrets exist in tracked files; do not commit new secrets or reshuffle them casually.
