- Phone camera or photo -> WebGL shader that classifies every pixel against
the sampled screen colour; colour-blind friendly (stripes, motion, words)
- Views: Spill, Screen (flat colour), rough live Key, Evenness
- Spill = worse of lean toward the screen hue and the green/blue despill
limit, tuned on a real Alexa car-interior plate (teal screen, green bounce)
- Plain-English verdict incl. widespread colour cast; tap for readouts
- Pick screen / pick white (neutral reference), freeze, exposure/WB lock
- Service worker caches each /set page under its own path (spill page no
longer overwrites the markers page offline); link from /set
