/* ===========================================================================
 *  styles.css  —  HHE donation app (index.php + thank-you.php).
 * ===========================================================================
 *
 *  Goals: clean, accessible, mobile-first, lightly branded (HHE), and
 *  dependency-free (no CSS framework, no web fonts pulled from a CDN).
 *
 *  Structure of this file:
 *    1. Design tokens (CSS custom properties)
 *    2. Base / reset-ish defaults
 *    3. Layout: page, brand header, card, footer
 *    4. Form fields, labels, hints, errors
 *    5. Components: frequency toggle, amount chips, buttons, spinner
 *    6. Thank-you page bits (summary list, tax line, success check)
 *    7. Accessibility helpers + reduced-motion
