/* checkout.css - Shared PayPal modal and checkout styles */

/* 
 * PayPal Modal Management:
 * - Product page modals: Defined in HTML (product.html, index.html) for direct product checkout
 * - Cart drawer modals: Defined in HTML within cart drawer component scope for proper Alpine.js binding
 * - All modals share the same CSS classes (.modal, .pp-modal, .sheet, etc.)
 * 
 * Note: Cart modals must be in HTML (not JS-created) because Alpine.js needs to process
 * the x-show, x-transition, and @click directives at initialization time.
