/* =================================================================
   Department site stylesheet
   Extracted and generalised from kvad.html (blue) and
   flyer/cogneuro.html (red). Single source of truth for the whole
   site: bespoke unit pages, the news section, and ordinary content.

   THEMING. Everything keys off the custom properties in :root.
   To retheme a page or the whole site, change only --brand-deep and
   --brand-bright (plus the matching tints). Nothing else needs editing.
   The two unit pages historically differed ONLY in these values:
     blue  unit: --brand-deep #002855  --brand-bright #0050c8
     red   unit: --brand-deep #7d1d2c  --brand-bright #b81d2e
