/*
 * HanlanOS Unified Design System
 * Single source of truth for all HanlanOS apps
 * Based on Travel Planner palette with comprehensive component library
 *
 * Rules:
 * - No emojis in UI (use icons or text labels)
 * - Consistent dark theme across all apps
 * - Inset borders on cards (not regular borders)
 * - Subtle hover effects with gradient overlays
 * - Sans-serif for UI, optional serif for reading
