/**
 * 상품 상세페이지 스타일 (260916_Review10 §6) — 상품 상세에서만 로드 (functions.php rxg_wire_product_detail_assets).
 *
 * 역할: Breadcrumb · 구매영역(갤러리/요약 훅 출력 간격) · 상세 콘텐츠(§13) · 제품정보 Accordion(§4) · 최근 본/연관 그리드(§22) 톤.
 * Source of Truth: 디자인 토큰은 테마 style.css(:root --w-* / --s* / --r-*) 를 그대로 사용, 없으면 폴백값.
 * 규칙: 가격 블록(.rxg-price-block, 플러그인 shop.css)·배지·장바구니 버튼의 시각 규칙은 건드리지 않고 배치 간격만 조정.
 *      에이전트 A 의 추천정보·회원가 비교 블록(summary 훅 6)은 .summary > * 공통 간격 규칙으로 자연 배치.
 * 확장: Accordion 항목은 .rxg-pd-acc__item 단위 — 새 항목도 같은 클래스로 추가하면 스타일 자동 적용.
