/* ============================
   SCROLL REVEAL ANIMATIONS (shared across public pages)
   Sections and cards start hidden/offset, then smoothly fade + slide
   into place as they scroll into view (via IntersectionObserver in
   script.js). Cards within a grid stagger slightly via nth-child delay.

   Kept in its own file (not merged into shared.css/about.css/gallery.css/
   program.css) since those files aren't present in this environment —
   writing into them blind risks overwriting real content I can't see.
