/**
 * Zoom Game (ZoomZoo)
 *
 * Everything is scoped under .fzg. Brand tokens are inherited from the theme
 * where it defines them, with the WunderWild palette as fallback. Responsive
 * sizing uses container queries (cqi), not media queries, so the game adapts
 * to whatever column the shortcode lands in.
 *
 * Motion notes: the zoom is a transform transition on .fzg-zoom; the Ken Burns
 * drift is a separate animation on .fzg-drift so the two never write the same
 * property. Drift is paused while a zoom transition runs. Everything animates
 * transform/opacity only - nothing here can trigger layout.
