   GAU Staff Portal — design system
   Colours sampled from the Garissa University seal:
     olive green ring  → primary (deepened for contrast)
     lime ring         → accent (active states, focus, highlights)
     camel brown       → secondary accent
   Built on Bootstrap 5.3 (vendored locally) so legacy fragments and
   modals pick up the theme automatically. Light + dark themes.
