/* Reveal animation — progressive enhancement only.
   Content is visible by default; it is hidden-then-faded-in ONLY when the
   early inline script in <head> has confirmed JS is running (adds .js to
   <html>). This means the animation never hides content from users whose
   JS fails to load/run, or from crawlers that don't execute JS. */
