/* ==========================================================================
   Landmark Finance Hub — Design System
   Direction: premium fintech-ops SaaS (Stripe/Linear/Vercel-inspired),
   glassmorphism, dark+light themes.

   Palette
     --brand-signal   #3355FF  primary action / focus / links
     --brand-landmark #C9A227  "certified / stamped" accent — ties to the
                                Landmark name, used sparingly for success
                                seals and highlighted totals only
     --bg-void        #0B0E1A  dark-mode canvas
     --bg-canvas      #F4F5FA  light-mode canvas
   Type
     Display: 'Space Grotesk' (geometric, technical — headings, big stats)
     Body:    'Inter' (UI text)
     Mono:    'JetBrains Mono' (filenames, counters, job ids)
   Signature element: the "certification seal" — a circular stamp motif
   used on success states, echoing a notarized finance document.
