   and easing. Every [data-reveal]/[data-grow] element is fully visible
   in its final state by default; script.js only adds .motion-ready to
   <html> (and therefore only this CSS takes effect at all) when
   IntersectionObserver is supported AND prefers-reduced-motion is not
   set, so a no-JS visitor, an older browser, and a reduced-motion
