    # R-737 (2026-09-30): wger's app login API (the mobile app's) signs JWTs with JWT_PRIVATE_KEY / JWT_PUBLIC_KEY — an
    # RSA pair the deploy's generators cannot make, and without it a CORRECT password answered 500. So the pair is made
    # ONCE by wger's own `manage.py generate-jwt-keys`, kept 0600 on wger's own data volume (a restore brings the same
    # key back), and loaded before the image's own entrypoint. Never printed.

      # R-712 (measured 2026-09-29 on 9202): behind traefik wger saw the request as http and refused a browser's

      # locked out EVERY household member for 30 min. Now only the targeted name, for 5 min (each try during a lock
      # restarts it — wger 2.7 hard-codes that — so short is kinder), counted in the database (the default cache

      # R-763 (2026-10-05): the image defaults both to True. After the install the admin exists (after_install sets its
      # password), so nobody needs wger's own sign-up: a stranger could make an account through the front door, and every
      # anonymous visit to the dashboard made a guest user row (wger's middleware create_temporary_user). Both read by
      # settings/main.py as env.bool (wger 2.7 L179-180); the sign-up view then redirects to the features page.

      # no default on EMAIL_HOST_USER / EMAIL_HOST_PASSWORD — so both stay defined-EMPTY here (the relay takes no
      # login; an absent one would stop wger at start). ENABLE_EMAIL is the gate: False unless the mail toggle injects
