/* ============================================================
   Platform shell — the shared page layout of the "one app" family
   (account.html, admin.html, /apps/, the apps) and the shared
   components of DESIGN.md ("White City"). Tokens only, from
   /assets/tokens.css (linked before this file); logical
   properties, RTL first. The top bar, app launcher and account
   menu come from /assets/bz-shell.js (<bz-appbar>, <bz-apps>,
   <bz-account>, <bz-app-icon>). The public pages load this file
   too, for the one button system (.btn = .bz-btn).

   Page skeleton:
