/* --- scroll reveal --------------------------------------------------------- */

/* The only rule on the site that hides content, and the reason `pre-reveal`
   exists as a class of its own rather than riding on `js`.

   `js` means "a script ran"; `pre-reveal` means "something has promised to
   un-hide this". The inline head script adds it and arms a 1.5s timer to take
   it off again if site.js never reports in, so the page cannot stay blank
   because a second file failed to load. Keeping the two flags separate is the
   point: `js` may gate decoration freely, but nothing else may gate TEXT. */
