@@ -29,6 +29,8 @@ Notes learned from the spec (verify before trusting):
 Project constraints (do not regress):
 - Backend is Django 6 + DRF with token auth (no session auth on the API);
   MariaDB/Redis come from docker-compose.yml.
+- Deployment will be Docker-based (compose); do not add systemd/cron unit
+  files for scheduling — use the container setup for timers/workers.
 - No server-side media processing: the home server cannot handle it.
   Compression/optimization runs client-side (WebCodecs + WASM in a worker)
   and the server only applies the result via POST /api/files/J-x/optimize/.
