/* Best-o-Masto - page-local styles for the live feature demos.
   Loaded only by apps/best-o-masto/index.html, on top of app.css. Every rule
   is scoped under .calm-app and every class is prefixed bm- 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 styles the replicas
   inside the stages.

   The demos are small HTML replicas of the app's post list. Stepped demos
   read a data-step attribute that app.js advances on a timer; the clickable
   ones are wired up in best-o-masto.js. With no JS every demo rests in its
   "before" state. */
