QA / perfection log (v4):
Rectification: NASCAR Cup decal -> 2.15:1 rectangle (aspect from Penske orthographic render)
IoU v3 -> v4 (vs rectified photo fill mask): 0.69 -> 0.9846
- R1 v3 glyph vs rectified team render: IoU 0.690; 1 too narrow, cap/flag wrong, mountains flat band.
- R2 photo-traced glyph (team render rectified by 4-pt grid): IoU 0.990 but render leaned ~6 deg due to 3/4 view.
- R3 re-rectified on NASCAR Cup door decal (2.15:1) so verticals are true; re-traced: IoU 0.985, slant 3 deg; outline rings re-measured (white 47, pale-blue 28 per 1000h); layered vector mountains replace flat band.
