/* 섬 미션 강조 층(2026-10-10 업그레이드) — docs/DESIGN_SYSTEM_v4.md 토큰 그대로(먹·흰 종이·빨강 한두 곳, 버튼 10px·패널 16px).
   index.html에서 v4.css 다음에 불러온다. 담는 것:
   1) 첫 안내창 = 미션 브리핑   2) 섬 미션 안내판(#mission-hub, 데스크톱 목록 / 모바일 한 줄)
   3) 미션 존 맨 위 미션 카드   4) 강의 견본 영상   5) 쿠폰 창 상태별 정리·도장 연출·다음 단계   6) 390px HUD 한 줄
   자동 움직임은 없다. 도장·발급 연출은 사람이 한 동작(다섯째 도장, 발급 버튼)에 답하는 한 번뿐이고 prefers-reduced-motion에서 끈다. */
