Redness, texture and coverage move independently — separating them catches a spot that's spreading even while it looks less angry.

WHAT THE MODEL MUST OUTPUT
1 · Skin / lesion mask
Per-pixel segmentation → feeds the heatmap (A), area cm² and patch boxes (B).
2 · Redness + texture per pixel
Calibrated a* (redness) & roughness, normalized with a color reference so lighting can't fake a flare.
3 · Embedding vector
A numeric fingerprint per photo → nearest-neighbour look-alikes (E) and "seen this before".
4 · Region + pose tag
Body part + aligned framing → clean time-lapse (C) and per-region trends.

Correlation, not proof. A high value means the two moved together — worth mentioning to your pediatrician, not acting on alone.
