   두 페이지에서만 add_stylesheet()로 불러온다. 사이트 공통 스타일과 섞이지 않도록 모든 규칙을 .yt 아래에 둔다.
   디자인 기준: 메인 "스타닥 마케팅 방식"(index.php#stardoc-sub-01, theme/ybusiness_1/css/style.css의 .main-02~13).
   - 배경: 검정·#1e1f23 위주, 밝은 구역은 흰색(.main-08)·회색(.main-13) 두 가지만.
   - 제목: 영문 2줄(소문자 / 대문자, 강조 단어 레드) 50px Bold + 한글 30px SemiBold(.main-06-01 등).
   - 소제목: 빨간 ▶ + 제목 + 영문 대문자(.main-07-02). 박스 제목: 검은 띠 + 빨간 왼쪽 선(.main-07-06 h4).
   - 항목 머리: "01." 빨간 번호 / 제목 + 회색 영문 + 오른쪽으로 이어지는 빨간 1px 선(.main-06-02-01-01 h3).
   - 박스: 빨간 1px 테두리 + 왼쪽 위 삼각형(.main-06-02-02 figure), 흰 1px 말풍선 + 꼬리 삼각형(.main-09-02 li),
     흰 박스 + 오른쪽 아래 매달린 삼각형(.main-02-02-02 div). 목록 점은 빨간 원(.main-06-02-02-06 li::before).
   - 글자: 기준 18px, 자간 -0.05em. 본문 20px Light. 작은 영문 장식 글씨는 Light·대문자·0.45em(카드 안 0.25em).
   - 모양: 각지게(라운드 0, 작은 칩만 2px). 유튜브 예시 화면만 유튜브의 라운드를 따른다.
   - 움직임: 30px 아래에서 떠오름(.main-06-02 > li.active의 sweep-y-reverse). sub/youtube/youtube.js가
     .yt에 .yt-anim을 붙인 뒤에만 숨김·등장이 걸린다(스크립트가 없으면 그대로 보임). */
