/* packopen.css — the card-opening reveal (js/packopen.js), shared by booster
   packs (terminal #packs) and the machine (gacha.html). A foil pack floats and
   tears, the cards rise into a stack, each back glows its tier once the chain
   has answered, a tap turns it with light to match its tier, and the haul
   ends in a grid. The sparks are a canvas (js/scene/reveal-fx.js); the rays,
   flash, foil and every move are here, so the reveal is whole without it.
   Under prefers-reduced-motion nothing moves: cards turn face-up in place. */
