 * Animated product demos on the v3 landing page (views/v3/landing/demos/*.ejs).
 * Each demo is a small app window built from the real ui3.css components, rendered at a fixed
 * design size (data-w × data-h) and scaled to its slot by public/scripts/ui3/landing-demos.js.
 * Scene choreography: the engine adds s1…sN to .u-lp-demo; `.on-N` pieces appear from scene N,
 * `.off-N` pieces leave at scene N. Raw colors live in the token block only.
