/**
 * ============================================================
 * Joyn LMS · 강사 워크스페이스 UI (모바일 재설계 v2)
 * 파일: joyn-lms/assets/css/joyn-lms-instructor-ui.css
 *
 * 강사가 보는 모든 화면(홈/수강생관리/강의관리/강의편집/수익)을
 * 모바일 앱 기준으로 재설계한 스타일 레이어입니다.
 *   · 하단 탭바(모바일) → 좌측 사이드바(데스크톱) 반응형 네비
 *   · 표 대신 상태 스파인 카드
 *   · 원장(ledger) 고정폭 숫자
 *   · 모달 → 바텀시트(모바일)
 * 모든 기존 클래스/데이터 속성/JS 훅은 그대로 두고 외형만 교체합니다.
