/**
 * Genre constellation — [genre_constellation].
 *
 * Two modes, one markup. The mu-plugin renders chips, a stage and a list of
 * genre blocks. With no JavaScript, or under prefers-reduced-motion, or if
 * WebGL is unavailable, the root carries .gc--static (or nothing at all) and
 * every genre block is shown as a card with a disc sized by track count: a
 * static chart. When the renderer comes up the root gains .gc--webgl, the
 * stage shows the planets, and the blocks become the side panel — only the
 * selected genre's block is displayed. Nothing is duplicated between modes;
 * the same buttons play the same songs.
 *
 * Scoped to .gc so it cannot leak. Colours ride the homepage's --sh-* tokens
 * where they exist and fall back to the same values where they do not.
