/* Quick Subtitles - page-local styles for the live feature demos.
   Loaded only by apps/quick-subtitles/index.html, on top of app.css. Every
   rule is scoped under .calm-app and every class is prefixed qs- 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 a few
   colour tokens and styles the replicas inside the stages.

   The demos are small HTML replicas of the Quick Subtitles window. With no
   JS (or with reduced motion) each one rests in a finished, readable state. */
