/* scroll-reveal.css
   Subtle, professional on-scroll reveal animations.
   Styles apply ONLY when JS is active (html.js-reveal), so if JavaScript is
   disabled or fails, all content stays fully visible — nothing is ever hidden.

   Usage: add class="reveal" to any element. Optional direction modifiers:
     reveal reveal-up      (default: rises from below)
     reveal reveal-down    (drops from above)
     reveal reveal-left    (slides in from the left)
     reveal reveal-right   (slides in from the right)
     reveal reveal-zoom    (gentle scale-up)
   Stagger a group: put class="reveal-stagger" on a parent; its .reveal
   children animate in sequence.
   Tune per element with inline vars, e.g. style="--reveal-distance:28px"
