All app and uvicorn logging now goes to logs/app.log (rotating, 10MB x5), and a catch-all exception handler logs full tracebacks there before returning a generic 500 — so an error is traceable to its cause without depending on how the process was launched. logs/ is gitignored, like the other runtime artifacts.
