/* ------------------------------------------------------------------ *
 * CC.demo — the animated explainer (public/js/demo.js builds the DOM).
 *
 * Everything moves with transform/opacity only, driven by CSS keyframes
 * that are switched on by the .is-live class on a scene. JS only decides
 * which scene is live and when, so pausing is a single class:
 *   .ccdemo.is-paused → animation-play-state: paused on the whole stage.
 *
 * The stage is a fixed-ratio box; its contents are laid out on a
 * 20em × 12em canvas and the em is sized from the stage width, so the
 * drawing scales as one piece and never shifts the page while running.
 * Direction: positions use logical insets, movement uses --dirx (1 / -1).
