/* Playoff 2.5D avatar — tier flourishes & tile chrome
 * ───────────────────────────────────────────────────────────────────────────
 * Drop this stylesheet next to avatar-renderer.js. All selectors are scoped
 * with the `.pa-` (Playoff Avatar) prefix so they won't collide with your app.
 *
 * Token defaults are listed at the top — override them in your app's root
 * (or a parent of `.pa-tile`) to re-skin without forking this file.
 *
 *   --pa-paper       warm card background (default #F4F1E8)
 *   --pa-paper-edge  inner stroke on the card
 *   --pa-radius      tile radius
 *   --pa-tilt-perspective  perspective for the parallax tilt
 *
 * The five tier classes are: pa-tier-{base|common|rare|legendary|mythic}.
 * They escalate visual richness:
 *   base       clean card, idle bob only
 *   common     soft blue halo
 *   rare       warm halo + shimmer sweep
 *   legendary  warm bg + dual halo + shimmer
 *   mythic     orbital rings + sparkles + tinted bg
