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
