   Motion primitive

   Entry animations are gated on `html.mb-js`, a class added by
   assets/js/animate-on-scroll.js at runtime. That script is only enqueued on
   the front end, so inside the block editor the class never exists and content
   renders fully visible and static — no disorienting invisible text while
   editing. It also means content is visible if JS fails or is disabled.
