/*
 * RahkarTheme — Add-to-Cart modal styles.
 *
 * Loaded only on shop / product / archive / cart pages (see
 * inc/cart-modal.php condition). No bytes ship to the blog, home, or
 * static pages.
 *
 * Layout model:
 *   - Mobile (< 768px): bottom sheet. Panel slides up from the bottom
 *     edge via translateY. A small "handle" hint sits at the top.
 *   - Desktop (≥ 768px): centered card. Panel scales 0.96 → 1 and fades.
 *
 * Animation model:
 *   - State toggled by a single `data-state` attribute on the container
 *     (managed by cart-modal.js). All transitions are GPU-only — transform
 *     + opacity, no width/height/margin animations → no layout thrash.
 *   - The panel uses `contain: layout paint` so internal repaints don't
 *     invalidate page layout.
 *
 * RTL: theme runs direction:rtl globally; nothing in this file uses a
 * directional `left`/`right` for content flow. The desktop centering uses
 * `left: 50%; translate(-50%, -50%)` which is physical and direction-
 * independent.
 *
 * Tokens: pulls from theme.json palette/spacing where possible, with
 * literal fallbacks so the modal still renders coherently if any palette
 * slug is later renamed.
