/* Subha Bihani admin — "सिक्नुहोस्" (Learn) mode: the Learn screen, the ways in, and the lesson
   overlay (spotlight, moving hand, caption panel). Uses the colours of styles.css.
   No inline styles (CSP): tour.js only writes CSS custom properties through the CSSOM:
   --sx --sy --sw --sh (spotlight box), --fx --fy (fingertip), --vvt --vvb (keyboard/visual viewport),
   --p (progress 0–1), --tour-move (how long the hand takes to move). */
