   normal opacity (1) — there's no separate "hidden" base state that could

/* ---------- Scroll reveal ----------
   Visible by default (no-JS / not-yet-run state). main.js adds
   html.reveal-ready only once it has actually attached an
   IntersectionObserver to every [data-reveal] element — so the hidden
   state is only ever reachable together with the code that clears it. A
   slow script, a JS error earlier in the file, or no JS at all just means
   the page renders instantly with no animation instead of staying blank. */
