/**
 * NUMISPEC: CAUSAL MINIMALIST EDITION
 * Design Baseline: Causal (minimal.gallery/causal / causal.so)
 *
 * Design System:
 * - Modern Neo-Grotesque Typography (Inter, Plus Jakarta Sans)
 * - Negative letter-spacing, tight kerning, high visual hierarchy
 * - Alabaster canvas (#FAFAFA / #FFFFFF) with obsidian typography (#09090B)
 * - Subtle 1px hairline borders (rgba(0, 0, 0, 0.07))
 * - Floating glassmorphic island navigation
 * - Rounded cards (14px) with soft ambient drop-shadows
 * - Symmetrical proportional fit for real coin and banknote slabs
