/* ==========================================================================
   Pikett · division demo "div-decks" (divisions/decks.html hero stage)
   A 3D stack of DOM slides for "Darn", a sample company made for this demo.
   1. Shell: toggle, counter, stack, ticks, caption (container queries on the stage)
   2. Storyline view
   3. Slide base: themes, type, motion primitives (live / static / reset)
   4. The nine slides
   5. States: intro, paused, reduced motion
   Geometry (slide size, stack position) is set by js/scenes/div-decks.js as
   --dk-w --dk-h --dk-l --dk-t --dk-bar --dk-story-t --dk-story-b --dk-hint.
   Every size inside a slide is in cqw of the slide, so a slide is laid out
   natively at any size (crisp type, identical line breaks).
