/* ============================================================
   DESIGN SYSTEM — Market Events Monitor
   shadcn/ui-inspired tokens + shared components

   Hallmark redesign (site-wide): editorial / Swiss-blue system.
   --blue is the richer cobalt accent (was #2563eb/#3b82f6); --font-display is
   DM Serif Display for headings (kept); --font-sans is Hanken Grotesk for
   body/UI; --font-mono is IBM Plex Mono for numbers/data/labels. (Previously
   Geist / Geist Mono — swapped for a pairing with more character that doesn't
   read as "generic AI dashboard default".) Every page that already consumes
   these tokens picks up the new look automatically; no per-page hardcoded
   colour/font should bypass them. --font-body/--font-label are aliases of
   the same values for code that prefers that naming.
