/**
 * Dealer Cart Styles
 *
 * Owns cart drawer + /cart/ fallback page styling. Loads sitewide because
 * the drawer is mounted in the header on every page.
 *
 * Source of truth: docs/systems/CART-SYSTEM.md
 *
 * Depends on: dealer-components, dealer-header.
 *
 * Header.css still owns the panel-family shared visual language
 * (background-color, header bar, title typography, scroll-hint shadow,
 * panel-family motion + reduced-motion, body scroll lock) — those rules
 * apply to .dealer-menu, .dealer-cart-drawer, and .dealer-search-screen
 * together and don't belong to cart alone.
