/* AI 강의 도우미 화면(/ai, /ai/week-NN). 대화 화면은 v3 "조용한 대화창"(아래 ── 대화 화면 v3 ──).
   색·서체는 form.css 의 브랜드 토큰(--canvas, --ink, --orange-action …)과 Pretendard 를 그대로 쓴다.
   방향: taste-skill 앱 화면 규칙의 editorial-greeting(.taste-skill/app/direction.json) — 가운데 열, 바탕에서 한 단계 밝은
   톤 패널(테두리·그림자 없음), 강조색은 행동(보내기·질문하기)과 근거 번호에만. 떠 있는 입력창만 그림자를 갖는다.

   틀: 머리글과 같은 좌우 여백 max(24px, 50vw - 620px) → 1280px 화면에서 내용 폭 1232px.
   대화 화면 1232 = 220(주차) + 32 + 628(대화) + 32 + 320(근거 구절)
   목록 화면 12열: 1232 = 12 × 76 + 11 × 32 → 열린 주차 8열(800) + 32 + 안내 4열(400) */
