    ``CreateDuelRoomView`` resolves ``catalog_service`` via DI and calls
    ``load_data(media_type)``. Without an override it hits the real singleton,
    which reads a catalog JSON from disk and caches it -- making these tests
    depend on disk data and on the singleton's (suite-order-dependent) state.
    A scoped ``providers.Object`` override returns the mock directly, bypassing
    the persistence sub-container. We scope with ``with`` (never
    ``reset_override()``) per the games conftest guidance.
