/*
 * These base rules from the consolidated reference-theme must appear AFTER the @media

 * This also ensures .page-intro rules beat .product-intro rules from components.css
 * at desktop widths (same cascade-order mechanism).
 *
 * At ≤680px, .product-intro h1 in the block above intentionally wins (it appears
 * after .page-intro h1 in that block, matching reference-theme's original order).
