/*
 * FROSTFIRE NIGHT — "Frosted Glass" (r547 redesign)
 * ---------------------------------------------------------------------------
 * This is NOT a recolour of Celestial Night. It is a different design language:
 *
 *   Celestial            Frostfire
 *   -----------------    -------------------------------------------------
 *   Georgia serif        monospace, uppercase, wide tracking
 *   carved arch corners  sharp 0–2px corners, 45° cut (clip-path) on one side
 *   opaque navy + gold   translucent frosted glass over a hairline lattice
 *   gold filigree        ❄ / ◇ marks, chevrons, 1px double rules
 *   floating nav pill    full-width nav split into cells by hairlines
 *   3 separate stat cards  one continuous hairline strip with dividers
 *   art behind the text  art inside a clipped rhombus panel on the right
 *
 * Rules: paint + geometry only. No board, pawn, die, pip, coin-value or
 * interaction selector is touched. Everything is scoped to the theme.
