/*
 * cart-exp.css — Experimental cart redesign (Emil Kowalski principles)
 *
 * Key fixes vs v1:
 * - Base style.css already has button:hover translateY — don't duplicate
 * - Use @starting-style for entry animations (Chrome 117+, Safari 17.5+, FF 129+)
 * - Focus on VISIBLE design changes, not just transitions
 * - Physical interactions: scale on press, spring easing
