/* ============================================================================
   QENTRA TECH — product showcase pages.
   Layered on tokens.css + base.css + front.css. Adds the product opening, the
   chapters, the hand-over cards, and the motion that the pages are built on:
   lines DRAW where something is being measured, blocks RISE in reading order,
   live things PULSE. Everything is a layer — every page is complete with
   scripts off and with reduced motion on.
