/*
 * Celebration Church Potluck Signup — styles.css
 *
 * Design intent: Warm, light, inviting — "Hawaiian-shirt Sunday" energy.
 * This is a church-facing volunteer coordination tool, not a dark dashboard.
 * Serif headlines (Georgia) anchor the church aesthetic; system sans body
 * keeps form elements readable on phones. Palette centers on warm cream
 * (#faf6f0), deep church-red accents (#7a2c2c), and gold for offline badges.
 *
 * Mobile-first: 375px base (iPhone SE), 768px 2-column grid, 1024px desktop.
 * WCAG AA contrast preserved throughout; focus rings always visible.
 *
 * Sections (in order):
 *   1. CSS Custom Properties (:root)
 *   2. Base Reset
 *   3. Typography
 *   4. Layout
 *   5. Components
 *   6. State Variants
 *   7. Utilities
 *   8. Print Styles
 *   9. Responsive Breakpoints
