feat(phase3a): 음악 랜딩·샘플 라이트 재스킨

app/music/page.tsx·app/music/samples/page.tsx 순수 시각 변경(className/style만).
다크 히어로(bg-black/gradient)와 샘플 카드의 violet 그라데이션·블러 글래스
CTA 밴드를 --jsm-navy/accent/accent-soft/surface-alt/line/ink 토큰으로 치환해
사주·showcase 재스킨과 동일한 navy 밴드 무테두리 flat + 흰 CTA 관용구로 정렬.
영상 이모지는 인라인 SVG 아이콘으로 교체. 데이터·구조는 변경 없음.
