/*!
 * kit-gallery-slider — admin-kit gallery 모듈의 프론트 슬라이더 스타일.
 * Swiper 6+ 기반. Swiper 자체는 사이트가 로드 (bundle 또는 CDN).
 *
 * 마크업(고정 클래스):
 *   <div class="kit-gallery-slider swiper">
 *     <div class="swiper-wrapper">
 *       <div class="swiper-slide"><img src="..."></div>
 *       ...
 *     </div>
 *     <div class="swiper-pagination"></div>
 *     <button class="kit-gallery-slider__btn kit-gallery-slider__btn--prev">…</button>
 *     <button class="kit-gallery-slider__btn kit-gallery-slider__btn--next">…</button>
 *   </div>
 *
 * 오버플로우 방지 규칙:
 *  - .kit-gallery-slider = width:100% + overflow:hidden + box-sizing:border-box
 *  - .swiper-slide       = flex-shrink:0 + width:100% + min-width:0 (flex 컨텍스트에서 컨텐츠가 튀어나오지 않도록)
 *  - img                 = max-width:100% + object-fit:contain (원본 비율 유지, 최대 크기 제한)
 *  - 사이트 CSS와 충돌 시에도 !important 로 layout 보호.
