/* Soontek harness page
   Loaded after soontek-tuotesivu.css and only by harness/index.html. The shared
   file still gives the ground, the type, the header, the footer, the button and
   the pinned background band; everything here is prefixed hx- and scoped to
   body.hx so the other three product pages do not change.

   Motion rules, in one place:
   - Every base style is the FINAL state. Animations start from hidden and run
     into it, so the page reads the same with no script, with a script that
     failed to load, and with prefers-reduced-motion.
   - Hidden-until-revealed states exist only under html.js, a class that
     skriptit/harness.js sets itself. No script, no class, nothing hidden.
   - Scroll reveals get .is-in from the script. Looping demos start on .is-in
     too, so they do not run before anyone can see them. */
