/* 20, results (site/sections/20-results.html). Linked by scripts/build-home.mjs.

   Three layouts from one markup:
   - Pinned (desktop, engine mounted, .sc-act--pinned): a two-column stage.
     The left column holds the heading and the index; the right column is
     the deck. site/js/acts/20-results.js writes per card:
       --ke  its own entry, 0 (hidden below the deck's edge) to 1 (in place)
       --kd  how many cards sit in front of it
     One translate3d plus a scale, never transitioned, so it cannot lag the
     scroll. A covered card steps up and back (a tab above the front card);
     the third card back fades out. Defaults (--ke: 1 on the first card, 0
     elsewhere) match frame 0, so nothing flashes before the first frame.
   - Wider screens without the pin (reduced motion, no JS): a grid.
   - Phones: a sideways rail with scroll snap. */
