/* The top bar shared by every page on the site, Blue Command included (it loads /sitebar.css and /sitebar.js
   from here). Markup comes from sitebar.js; a page only provides <header id="sitebar" data-current="...">, and anything
   inside it (e.g. Blue Command's connection status) is kept in the bar's page slot. Self-contained: it relies only
   on the tokens in theme.css, so it looks the same whatever stylesheet the page itself uses. */
