/* Progressive enhancement:
   - By default (no JS / module blocked), content should be visible.
   - When JS runs, we add `html.js` and enable reveal transitions.
   - Fallback animation ensures content is always shown after 1.4s
     even if IntersectionObserver never fires (e.g. file:// protocol). */
