/* Visual kit (Task #1896): takeaway, steps, side-by-side, live stat, figure,
   annotated figure. Markup comes from src/_lib/visual-kit.js, motion from
   js/visual-kit.js. Only these blocks ever animate, never body text.
   Motion is transform + opacity only, so it cannot shift layout (CLS). */

/* ---- Scroll reveal --------------------------------------------------------
   Chrome and Safari 26 do this with no JavaScript (a view() timeline). Other
   browsers get the same effect from js/visual-kit.js, which only hides blocks
   that start below the fold. With reduced motion, or no JS, blocks just show. */
