/* lib/topbar.css — shared Bloomberg-style topbar component.
   Loaded by every page that mounts <div id="topbar-mount" data-active="…">.
   Owns ALL styling for the three-row dark header: ticker, brand, nav. The
   page CSS only handles page-specific chrome below this strip.

   Active-link highlighting is driven by `data-active` on the mount div
   (rendered into class="active" on the matching <a>).

   Theme: dark forced, regardless of body.light — terminal chrome stays
   dark across both modes.
