/* Chapterize - page-local styles for the live feature demos.
   Loaded only by apps/chapterpod/index.html, on top of app.css. Every rule is
   scoped under .calm-app and every class is prefixed cp- so nothing here can
   collide with the shared calm components. The hero, tiles and stepped demo
   runner come from app.css / app.js; this file overrides their colour tokens
   and styles the replicas inside the stages.

   The demos are small HTML replicas of the Chapterize window: a player bar
   over a list of chapters. Stepped demos follow the data-step attribute that
   app.js advances; the clickable ones are driven by chapterpod.js. */
