/* assets/games/matching.css — v1.0 (Beta)
 * Match Game — Maryland MHIC beta launch (2026-06-15).
 * Mirrors the dark games aesthetic of wordfinder.css + crossword.css.
 * Per-state color tokens come from state-themes.css (`body.state-md`, etc.).
 * --xword-primary / --xword-accent are reused for visual parity with the
 * other games — when a canonical state-brand palette lands (see state-
 * themes.css comment), these reference the same vars. */
