/*
 * it-hp Synology NAS 판매 페이지 전용 스타일 (/sub/synology 목록, /sub/synology-product 상세)
 * - style.css(Vite 번들)에 섞지 않고 $additional_css 훅으로만 로드한다.
 * - 테마 변수(--blue-*, --border-*, --text-*, --bg-*)를 우선 쓰고 단색만 쓴다(그라데이션 없음).
 * - 접두사: 페이지 공통 .syn-*, 쇼핑 화면 .sys-* (TP-Link 의 .tpl-*/.tps-* 와 겹치지 않게)
 * - 바로구매(결제)가 없으므로 결제·배송지 스타일은 두지 않는다.
