/* ============================================================================
   LedgerBridge — institutional design system
   Not a theme. Four rules, enforced everywhere:

   1. TYPE      Inter for UI · Source Serif 4 for page titles only ·
                JetBrains Mono for every number, ID and code.
                Serif never appears on a sub-panel — only where a document
                would put a title (page h1, statement headers, login).
   2. COLOR     #fafafa base, white panels, #e4e4e7 hairlines, ONE accent
                (deep forest #0f4c3a). No gradients. No glow. No pastel glass.
   3. STRUCTURE 1px borders and whitespace do the separating — never heavy ink
                rules chopping up a data grid. Radii 4–6px, never pills-on-pills.
   4. DATA      Right-aligned tabular numerals; a zero is muted, a variance
                is loud. Never bold a zero.
