/**
 * LedgerCap — HIG design tokens (render-blocking, unlayered).
 * Ported from the ScentCap 3.0 system (via VaultCap 6): semantic colours for light / dark / increased contrast,
 * SF system type at 17pt body, 44pt targets. LedgerCap keeps its own accent: bahi-khata brass.
 * Theme = `data-theme` on <html> and <body> (js/theme-boot.js, App.applyTheme); dark is the default.
 * The bottom block bridges legacy tokens (--psx-*, --lc-brass/maroon/folio, --text*) so older screens inherit.
