   SCROLL REVEAL BLOCKS
   ─────────────────────────────────────────
   FIX BUG 4 & 8:
   The transition here is the CSS fallback.
   GSAP overrides this with inline styles.
   The key fix: we no longer toggle this class
   off (see script.js initScrollReveal fix).
   Once 'is-visible' is added it stays forever,
   so content is always visible after first reveal.
