/* ==========================================================================
   Fuqua Course Compass — "Industry" blueprint design system.
   Imported from the Claude Design project (Event Feed.dc.html). Barlow /
   Barlow Condensed type, a neutral canvas with a single blue accent ramp,
   squared hairline surfaces, and wireframe "+" corner registration marks.
   Legacy class + variable names are preserved so the existing markup and the
   inline styles in js/*.js keep working — the older Duke-navy variables are
   just remapped onto the new palette.
