Hold W for three seconds, then screenshot

The bug report says: walk into the north wall of the hangar for a few seconds and the camera clips through. QA reproduced it once. Nobody can reproduce it twice.

Games aren't click-then-assert. They are input held over time, and the display service has verbs for that. POST /keyboard/key-down with key: w and holdMs: 3000 presses and releases on the server's clock, not a tester's finger. input/drag with steps: 120 sweeps the mouse instead of teleporting it. input/act takes a screenshot after each step, and screenshotRegion crops to the viewport so the diff ignores the debug HUD.

The repro is a JSON body. It runs against the nightly build's container every morning, and the clipping frame lands in the ticket with a timestamp, from a machine that never gets bored of walking into walls.

The repro is a request, and the request doesn't get tired.
