/*
 * ============================================
 * FLOW THEME TEMPLATE
 * ============================================
 * 
 * HOW TO USE:
 * 1. Copy this file and rename it: my-theme-name.css
 * 2. Change ONLY the variable values below (the parts after the colon)
 * 3. DO NOT rename any variables - the HTML depends on these exact names
 * 4. Add any extra component styles BELOW the :root section
 * 5. To test: replace the current theme CSS link in your local copy
 *    or use browser DevTools to paste your :root overrides
 *
 * CONSTRAINTS:
 * - CSS only (no JavaScript)
 * - Must work with the existing HTML structure
 * - Responsive (mobile-first)
 * - WCAG AA contrast minimum (4.5:1 for text, 3:1 for large text)
 * - Use https://webaim.org/resources/contrastchecker/ to verify
 *
