/**
 * Antfarm Design System v2.0
 * ============================================
 * Warp-inspired, terminal-first, flat design
 * Based on Shell Design System v5.0
 *
 * Philosophy:
 * - Terminal-first aesthetic (Warp.dev inspired)
 * - Flat design: NO shadows, NO glows
 * - Warm off-white text on deep black
 * - ANSI-inspired accent colors
 * - Mobile-first with 44-48px touch targets
 * - Monospace typography for data/CLI elements
