/* ==========================================================================
   CacheYourBrain — site design system (app-shell edition)

   The site behaves like an app: the viewport never scrolls vertically.
   Layout = top bar / content canvas / status bar. Content that exceeds a
   screen flips horizontally between .page panels (js/pager.js) or sits in
   sub-tabs (js/tabs.js). Overflow inside a panel scrolls internally only
   (.page-inner, .workspace-sidebar, .workspace-main).

   Base theme is fixed (dark slate). Only --accent / --accent-glow shift per
   persona; the showcase window is themed via the --w-* variables.
