/*
 * Umrah2Go — Mobile Bottom Sheet Styles
 * FILE: assets/css/u2g-mobile-sheet.css
 *
 * Depends on: u2g-tokens.css (design tokens must load first)
 *
 * Covers:
 *  - .u2g-sheet-wrap / .u2g-sheet — base bottom sheet component
 *  - .u2g-mob-bar — persistent sticky cart bar
 *  - Cart sheet content — .u2g-sheet-cart, .u2g-sheet-item, etc.
 *  - Filter sheet content — .u2g-filter-sheet-content, .u2g-fsg, pills
 *  - .u2g-mob-filter-bar — filter trigger row on mobile
 *
 * Only renders visually on screens <= 960px.
 * Desktop gets display:none on the mobile-only elements.
