Module ui_only 

The UI-only scene: egui drawn into a frame with no mesh source and no camera.

Ported from the ui_only_draws_without_a_camera snapshot test: the frame shape that used to produce nothing, because the renderer bailed out when the world held no camera. The snapshot ui_only.webp freezes the second frame — the first only warms egui’s font atlas up.
