Squashed from work; the fine-grained history is under tag archive/work-2026-08-26: - fab: a 3D creation shell and the viewer built on it - raytrace: the traced pane starts coarse and doubles to native, with the raster underneath - fab: a colour picker, a material's textures, and dials that move the scene while they drag - texcomp: the block codec and the container every texture will travel in - fab: FAB_PROBE_MAT — per-material triangle counts, texture presence and uv spread in the roof probe
