The old `..._and_forever_rejected` asserted a 400 for keep_alive=forever; now that it's accepted, that PUT succeeded and WROTE gaming-rig into the process-global prefs, racing other tests. Rewrite read-only: assert the surface (5 presets, effective, enforced axes) and read gaming-rig=forever off the preset list — no write. Acceptance is covered on-glass (.116) + the pure policy tests.
