/* 🎯 대표님 지시(2026-09-25) — 제목(PRACTICE STRUCTURE)이 박스 밖 위로 나온 뒤 .smec-section의
   기본 margin-top:36px이 그대로 남아 제목-박스 간격이 과하게 벌어짐. 이 조합(.smec-section.bys-struct)만
   좁혀서 제목 바로 아래 박스가 붙어 보이게 함 — .bys-struct 단독 사용처(Reflection 등, smec-section 클래스
   없음)는 이 규칙 대상이 아니라 무영향.
   🚨 배포담당 발견(2026-09-25) — Training탭 "오늘의 문장 구조 훈련" 드릴 위젯(_bysStructTrainHtml,
   class="smec-section bys-struct bys-struct-train bys-struct-build")도 같은 두 클래스를 포함해 이 규칙에
   같이 걸림. 그 박스는 제목이 여전히 박스 안 첫 자식이라 margin-top:36px가 "제목-박스 간격"이 아니라
   "이 섹션과 앞 콘텐츠 사이 간격"으로 쓰이고 있어 12px로 줄이면 안 됨 — :not(.bys-struct-train)으로 제외.
   🚨 대표님 재지시(2026-09-25) — 12px로도 여전히 "같은 과 다른 파트(본문/한글본문/Reflection)"보다 훨씬
   멀어 보임. 다른 파트는 제목이 박스 '안' 첫 자식이라 title margin-bottom(14px, .bys-ee-title)만으로
   간격이 끝나는데, 이 박스는 제목이 밖에 있어서 title margin-bottom(10px, 인라인)에 이 박스의
   margin-top까지 더해져(기존 12px→합계 22px+테두리) 두 배 가까이 벌어져 있었음. margin-top을 0으로
   없애서 순수하게 title의 margin-bottom(10px)만 간격으로 남게 해 다른 파트(14px)와 거의 동일하게 맞춤. */
