/* spratapp.com - one stylesheet for every page.

   The visual language is the explainer video's: a dark stage, Inter set
   tight, a mono kicker over each section, keywords painted like SPRAT paints
   a cell, and light Ads Manager tables as the demo surface. Motion is all
   transitions on state classes, so anything a script does not reach still
   renders, and reduced motion simply skips the in-between. */
