/* ---------- Scroll reveal ----------
   Dipasang oleh main.js lewat IntersectionObserver.

   Reveal memakai `animation` + `transform`, BUKAN `transition` dan
   `translate`. Alasannya: komponen (kartu, tombol) sudah memakai
   `transition` dan `translate`/`rotate` untuk hover. Kalau reveal juga
   memakai properti itu, salah satu akan saling menimpa. Dengan
   keyframes, keduanya jalan bersamaan tanpa konflik.

   Delay per elemen: style="--reveal-delay:120ms". */
