/**
 * Mosaic grid layout for [tgg_random_games].
 *
 * Featured tile spans `featured_size × featured_size` slots; small tiles fill
 * the rest. Mobile breakpoints fall back to a simple 3-col grid (then 2-col
 * <380px) where the featured spans 2×2 (or 2×1 on very narrow screens).
 *
 * Depends on `tgg-frontend` + `tgg-badges`; load AFTER both.
