/* ==============================================================
   Countava Academy — guide chrome.
   Layered ON TOP of the app's app.css: we inherit every design
   token (--surface, --accent, --border, shadows, radii) so the
   guide themes in lockstep with the app, then add an "Academy"
   identity: warm editorial serif + a single amber signature.
   Guide-only classes are namespaced g-* / mk-* / demo-* / anim-*
   so they never collide with the app's component classes.
