/*
 * MOS/Crown-style odds board shell (docs/DECISIONS.md D6). Built only from
 * public/sports/css/tokens.css custom properties; no external fonts/CDNs.
 * Layout notes:
 *  - Desktop (>=768px): each event is a 3-row (home/away/draw) dense CSS
 *    grid row aligned under the .sb-grid-columns header. Market-group
 *    wrappers use `display:contents` so their price cells participate
 *    directly in the outer grid without duplicating markup for mobile.
 *  - Mobile (<768px): the same DOM becomes a card; the six market groups
 *    become a 2x3 mini-grid. Zero horizontal overflow at 375px is a hard
 *    requirement (7KS design QA).
