Per-vertex GS fog end-to-end (gs_stub emit incl. persp_emit5, gs_prim_list_feeder XYZ2->XYZF2 on PRIM.FGE, gs_make_sh3_scheduler_fixture.py F/FGE packing), new fog TBs, fidelity attribution tooling. Functional baseline before removing the dead bilinear lerp8 clamps (Codex: 161-node comb loop -> -0.042ns setup fail). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Convert a linear PSMCT32 framebuffer dump ($fwrite "%08x") to a PNG for visual triage.

# Word layout = PS2 PSMCT32 0xAABBGGRR (low byte R). Usage:

# gs_fb_to_png.py <fb.mem> <out.png> [width] [height] [scale]

# Defaults to the SH3 real-draw FB (256x120). No-op (exit 0) if input missing or PIL absent,

# so it can be chained after a sim without ever breaking the build.
