/* ==========================================================================
   Concept styles. Everything sizes against the stage container (cqw), so the
   Desktop / Tablet / Mobile preview toggle behaves like a real viewport.

   Motion rules shared by all concepts:
   - [data-reveal] + --i  : staggered entrance, gated by the Entrance lever
   - distances x var(--m) : the Intensity lever
   - durations x var(--dur): the Speed lever
   - var(--ease)          : the Easing lever
   Entrance animates the `translate` and `scale` properties, so `transform`
   stays free for layout, hover, and JS.
