   당현함 인터넷 쪽 공용 모양 · dh-shell.css   (2026-09-21 1단계)
   ──────────────────────────────────────────────────────────────────────
   ★ 무엇인가
     첫 화면·렌탈 2·사은품명단·약관 2·가전(화면 속 7벌)과 요금표·셋톱(dh-plans.css) 8벌에
     「똑같이」 들어 있던 머리띠·메뉴·발바닥·아래 띠 모양을 한 곳에 모은 파일입니다.
     인터넷 쪽 18장이 이 파일을 「맨 먼저」 부릅니다.
   ★ 규칙
     · 여기 있는 값을 고치면 18장이 함께 바뀝니다. 고친 뒤 18장의 ?v= 를 올리세요.
     · 화면마다 달라야 하는 것은 각 화면(또는 dh-plans.css)에 남아 있고, 이 파일보다 뒤에 와서 이깁니다.
     · 1단계는 「모양을 하나도 안 바꾸고 옮기기만」 했습니다(전후 전수 측정으로 확인).
     · 정수기 400장은 아직 css/dh-brand.css 를 씁니다(2단계에서 합칠 예정).
