/* ========================================================== app chrome
   The old header was three stacked bars before a single piece of content:
   a white brand bar, a "Signed in:" bar, and two rows of wrapped tab boxes.
   On a 375px phone that is about 190px — a quarter of the screen — gone
   before the nom sees a single earth.

   It is now two compact rows: brand and status, then a tab rail that scrolls
   sideways instead of wrapping. Who you are signed in as moves into a menu
   behind an initials button, because it matters (you must never act in
   someone else's session) but it does not need a permanent bar.
