PRIMARY OUTLINE REFERENCE: #1 above (NASCAR.com Paint Scheme Preview, 2026 Daytona 500 & Speedweeks). It is an orthographic side render, so it is already flat (no perspective rectification needed); upscaled 8x (bicubic) for tracing.

FINAL SPEC: fill #f2f2f2, dark-grey #4d4d51 outline (~50/1000) traced from preview, sharp corners.

METRICS
- Vector glyph vs preview number fill (geometry): IoU 0.9891
- Final rendered SVG vs preview: fill IoU 0.9833, outer silhouette IoU 0.9909
- Outline layers (outer->inner) traced-vs-uniform-offset IoU: [{'traced_vs_offset': 0.9606}]
- Preview glyph vs real photos (ECC homography alignment, IoU in photo space):
    4_noah_gragson/cand/c04.jpg: 0.9762 (number 101px tall)
    4_noah_gragson/cand/c00.jpg: 0.7081 (number 33px tall)
    gragson_0.jpg (2-11-26-Gragson, NASCAR.com) Rush-panel-rectified: 0.8165 (number 495px tall)
- v4 (previous, photo-traced) glyph IoU vs its own photo: 0.977

PERFECTION ROUNDS (v5)
- R1 preview trace fill IoU 0.989. Found v4's #4 (traced from a Rush-panel-rectified photo) was distorted: preview glyph vs that rectified photo only 0.817 -> the old square-panel assumption was wrong; preview now drives the shape.
- R2 grey outline traced (traced-vs-offset 0.961), mitred corners.
- R3 final render vs preview: fill 0.983, outer 0.991. Photo (qualifying side shot): 0.976.

Roof: checked against overhead Getty shots listed above (roof uses same glyph, roof colours from overhead photos).
