/* THE APP BAR (r71) — one header for every signed-in tool page that is not the builder:
   /sign, /sign/edit/<id>, /tools, /tools/<slug>, /forms/jito. Amit, 8 Nov: "once I go into
   Sign a PDF the entire navigation is gone … the header should be constant for all of
   these." It is /app's own bar — same navy, same 64px, same lockup, same account button on
   the right — with the page's name after a hairline. js/appbar.js adds the lockup and the
   account button; the page keeps its own title, language picker and actions in between.
   `header.appbar` outranks each page's older `.bar` / `.lockup` rules, so the bar looks the
   same whichever stylesheet loaded before it. The public signer page (/esign/<token>) is
   for outside recipients and does not get it. */
