/* Shared chrome above the dashboard's own header — index.html explains why it
   exists and how its two modes are chosen.

   Black with white text (21:1). There is deliberately NO crimson here at all.
   Crimson TEXT on black measures 2.11:1 and fails WCAG AA (4.5:1), so it was
   never an option for the lettering; a crimson rule under the bar was tried
   instead and removed on 2026-09-15 because it clashed with the purple
   masthead directly beneath it — black meeting dark purple reads cleaner than
   black, crimson, then dark purple. If this bar is ever reused above a
   lighter header, a rule may be worth revisiting.

   Deliberately NOT sticky. #navbar is `position: sticky; top: 0` and the data
   tables sticky their own headers; adding a second sticky layer above them
   means retuning all of those offsets for a 26px strip. It sits at the top of
   the document and scrolls away.

   Fixed black/white in every theme: institutional chrome should read the same
   on fusion, dark and greyscale. */
