     choice via data-theme (set by theme.js). Every text/background pair is >= 4.5:1.
     Light: core palette. MIT Red accent on white cards, Yellow highlight (the guide pairs MIT Red
     with analogous warm colours). Bright Red and Green are < 4.5:1 on white, so in light mode they
     are tints only, never text.
     Dark: near-black indigo canvas, one electric cyan accent, vivid violet reserved
     for decoration (login backdrop). Secondary text stays bright so small sizes never
     go muddy; selected states invert to solid cyan instead of tinting. Status colours go
     neon (mint / amber / hot coral) so they read at a glance on dark. */
