 * accent is not a single colour but a SCALE — the green/amber/red zones of a VU
 * meter. --mid and --hot are lifted from Roo Run's sun and heart colours, which
 * ties the portal to the game without borrowing its pixel-art style.
 *
 * No webfonts: a heavy system grotesque at extreme scale against wide-tracked
 * monospace labels is the studio-equipment vernacular, and it costs zero
 * network requests.
