/**
 * APH POOLS DESIGN SYSTEM
 * Version 1.0 - Phase 0
 *
 * SINGLE SOURCE OF TRUTH for all styling across the entire APH Pools application.
 * This file is used by both the public website and the QB Bridge dashboard.
 *
 * IMPORTANT: No hardcoded values in components - all styling uses design tokens (CSS custom properties).
 * Mobile-first approach: base styles are for mobile, then @media (min-width) for larger screens.
