/**
 * SVD Menu — Light Theme Design System
 * "Precision Hospitality" — Apple meets Stripe meets restaurant tech
 * 
 * DESIGN PHILOSOPHY:
 * - No glassmorphism, no grid overlays, no glow effects
 * - Distinctive element: "ink-on-paper" precision + architectural spacing
 * - Accent #00f0a8 adapted via darker functional variants for WCAG on white
 * - Typography-driven hierarchy with generous whitespace
