   Reserved.

   This file used to style the pre-design-system customer shell: a navy
   <header>, the sliding .top-bar-section menu and the yellow call-to-action
   pair on the home page. None of that markup exists any more — the shell is
   .app-header / .tabbar / .drawer in theme-shell.css, and the pages are
   built from theme.css components — so the rules went with it.

   It is still linked from _style_assets so page-level additions have an
   obvious home; put anything new in theme.css or a file-wise sheet instead
   unless it genuinely belongs to no single page.
