/* ──────────────────────────────────────────────────────────
   Jack-LM Shared Header
   Self-contained nav bar rendered by header.js into
   #app-header on every department page.

   Scoped under .bl-sh to avoid collisions with host styles.
   Colors use CSS custom properties that host pages can
   override — defaults match the Jack-LM dark-ish palette.
