 * MARL-BGs website: tokens, type and every shared component.
 * Look: the Moonlit Runefield. Night ink, moonlight silver, carved Cinzel titles,
 * rune rules with a lozenge, flagstone floors. Dark only, on purpose: the world is a night.
 * Color is meaning: Team A azure, Team B crimson (red means Team B and nothing else),
 * one color per class, crest gold only for ornament. Chrome stays silver and gray.
 * Contract: SPEC.md section 4. Page-author cheat sheet: shots/shell/HELPERS.md.
