/* SatStars landing page — and the results and centres pages, which share it.
 *
 * The page is a story about a score, and its visual language is the score's
 * own scale: 400 to 1600, drawn as a dial in the hero, a ruler in the climb,
 * and a bar under every result. Navy is ink, blue is progress, the star's gold
 * is the goal.
 *
 * Scenes: a `.scene` is taller than the screen and its `.stage` sticks while
 * the reader scrolls through it. motion.js writes `--p` (0–1), `data-step` and
 * `data-s` (every step reached) onto the scene; everything below reads those.
 *
 * The markup is written in each scene's finished state. The "not yet" states
 * are applied only under `[data-scenes]`, which motion.js sets when motion is
 * allowed — so without the script, and under reduced motion, every scene is a
 * plain section that already says everything.
