   luckymath 사이트 공용 모양 — 모든 쪽이 site.css 뒤에 읽는다 (2026-10-20)
   소개 페이지에서 정한 모양(색·글꼴·단추·머리·바닥·카드)을 다른 쪽도 함께 쓴다.
   색은 게임 화면에서 뽑았다:
     메인 머리띠 짙은 밤색 #2b211c · 단추 노랑 #ffc83d · 카드 크림 #fff7e6
     1학년 야구장 초록 #4aa543 · 하늘 파랑 #2e86c1
   제목 글꼴은 게임이 쓰는 주아(Jua) 서브셋(assets/fonts) — 서브셋이라 없는 글자가 있을 수 있다.
     긴 글·사용자가 쓴 글(공지 본문 등)에는 쓰지 않는다. 새 제목을 넣으면 tools/shoot-site.js 의 '없는 글자' 검사를 본다.
   읽는 차례: site.css → theme.css → (쪽마다) landing.css 또는 pages.css
