/* MiniGamePlanet — Brain Tests shared styles + site-wide badge styles.
   Each game page sets its accent via inline `style="--bt-accent:#xxxxxx"`
   on the .bt-main wrapper. All color values use the real MGP variables
   defined in mgp-core.css (--mgp-text, --mgp-text-muted, --mgp-text-heading,
   --mgp-surface, --mgp-border) so they adapt to light AND dark mode and
   stay readable when nested inside the dark-mode <main> (which is rendered
   on a near-white surface). Fallbacks default to readable LIGHT-mode colors
   so we never end up with white text on a white background. */
