 * Veri laboratuvarı (plan 106 A6), the `data` investigation drawn by lab-find-data.js. Colours come only from tokens.css
 * (chart-1..6 for categories and groups); no color-mix(). Each grade fits one screen of the explorer dialog at 1366×768
 * and 1280×720: two columns (plot | task panel), one column on phones. Motion is the JS drop-in (transform and opacity)
 * plus the button transitions, both off under body.reduced-motion.
