   No fade/slide-in animation: both CSS `animation` gated on
   [data-deck-active] and a JS Web Animations API equivalent were
   observed getting stuck at their "from" (opacity:0) state — the
   document's animation timeline can stall in some contexts (e.g. a
   backgrounded/thumbnail iframe, some presentation setups) and there's
   no reliable recovery. For a booth deck, reliability beats polish:
   content is simply always visible. */
