/* ==========================================================================
   MNX15 Design System — Components
   CSS translation of the design-system component library (originally authored
   as React components) for the server-rendered Handlebars storefront.

   All classes are namespaced `ds-` so they never collide with existing page
   CSS. They are opt-in: including this file changes nothing until markup uses
   the classes. Every value derives from the tokens in /css/tokens/*.css.

   Usage examples:
     <button class="ds-btn">주문하기</button>
     <button class="ds-btn ds-btn--secondary">취소</button>
     <span class="ds-badge ds-badge--active">배송완료</span>

   Component index: Button / KakaoButton, Input, Select, Checkbox, Radio,
   ProductCard, SizeSelector, PriceSummary, Badge, Navbar, SidebarMenu,
   Accordion, Modal, NoticeBanner.
