- Phones held sideways get the picture full height with a narrow control
column on the right (new `land` Tailwind variant), settings as a side panel
- Framing crop (Full / 16:9 / 1.85:1 / 2.39:1, default 2.39:1) applied to the
picture, taps and stats, so the verdict only counts what's in frame

- 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
