  note: Found 2026-08-19 by probing the Swagger UI shell at https://api.tum.app/ — its declared spec URL
    ./swagger.json returns the UI HTML (soft 200), the real document is one level down at /swagger/swagger.json.
    Pristine Swagger 2.0 copy kept at openapi/_original/tum-campus-backend-swagger.json; this file is
    a mechanical 2.0 -> 3.0.3 structural conversion of it, with servers[] filled from the live host the
    document was fetched from. No operation, parameter or schema was invented.
