/* ═══════════════════════════════════════════════════════════
 * 현장 강의 커리큘럼 페이지 — page-onsite-curriculum.php 전용
 *
 * 2026-09-06 css/onsite-booking.css 의 1466~2092 행에서 분리했다.
 * 분리 이유: 신청 페이지 쪽 1,465줄에 !important 5건 · gradient 6건 ·
 * --radius-xl(라이브 20px)이 있는데 커리큘럼 페이지는 그걸 하나도 쓰지
 * 않으면서 매 요청 내려받고 있었다. 선택자 교집합이 0이라 잘라내기만 하면 됐다.
 *
 * ⚠️ 아직 남은 v3 위반 (시안 확정 후 정리):
 *   .curr-section-headline em → linear-gradient 형광펜 밑줄
 *   .curriculum-cta-btn · .curr-pkg-mod-chip · .curr-pkg-tag → --radius-full (pill)
 *   .curr-pkg-card → --radius-lg 은 라이브에서 16px (v3 카드는 8px)
 *
 * ⚠️ 다음 단계 예정 — body.page-template-page-onsite-curriculum 에
 *    --cr-* 스코프 토큰을 깔아 라이브 토큰 함정(--radius-lg 16px 등)을 끊는다.
 *    이 후크는 라이브 body 에 이미 찍혀 있어 마크업을 건드릴 필요가 없다.
 *    값이 바뀌는 시각 변경이라 레이아웃 시안이 확정된 뒤에 한다.
