详细描述

Screen-space single-bounce GI (SSGI).

Samples scene color (RGB = lit radiance) plus hardware D32 depth, and adds bounced light from nearby occluders. Manual fullscreen overlay (applyFromScene / applyFromDepth). The 3D default path does not auto-apply it: sampling lit scene color reprints nearby props onto the floor as swimming ghosts. Mesh shaders still add hemispheric sky/ground

• wrap fill. Tests may still pass a packed RGBA8 (RGB = albedo, A = linear depth) via applyFromDepth.

Quality presets ("low" | "medium" | "high") tune sample count and radius.
