 * 카메라 전체화면 모드 - smart 디자인 호환 패치

 * smart-hero, smart-steps, smart-exam-card, smart-subject-card,
 * preview-panel, result-panel 같은 새 섹션이 생겼습니다.
 *
 * 기존 app.css는 예전 구조 기준으로 일부 패널만 숨기기 때문에,
 * 새로 만든 OCR 인식 이미지(#screenView)가 카메라 화면 위에
 * 같이 보이는 문제가 발생합니다.
 *
 * 해결:
 * - 카메라 실행 중에는 camera-card만 남김
 * - OCR 인식 이미지 / 가채점 현황 / 시험정보 / 선택과목은 숨김
 * - 카메라 카드 안의 제목/버튼/안내문도 숨기고 실제 cameraFrame만 표시
