/* ===========================================================================
   Mage HQ — the app frame (layout.php render_header; behaviour in shell.js)
   After macOS and iOS. On a computer: a floating glass sidebar with the
   Settings app's coloured tiles, sections that fold and a rail of icons,
   and a toolbar laid over the page that turns to glass once the page
   scrolls. On a tablet the sidebar is a drawer. On a phone: a navigation
   bar whose title appears when the page's own heading scrolls under it, a
   glass tab bar beside a round New button, and sheets for More and New.
   Loaded after style.css and sales.css; colours come from style.css.
