   Home-page animations

   Everything below is opt-in: scoped to `body.has-anim` which site.js adds
   only on the home page (data-page="home") and only when JS + the relevant
   browser APIs are present. If the JS bail-outs at any step the page still
   renders fully — no flash of invisible content for users who hit a JS
   failure or have it disabled. The reduced-motion media query at the end
   force-disables every animation for users who prefer it.
