/* 가닥 홈페이지 — Gadoc 디자인 규칙(ios/Gadoc/Design/Theme.swift)을 따르되, 웹은 필름 사진과 어울리는
   자연스러운 웜 톤으로 대비를 낮춘다.
   - 웜 아이보리 바탕, 로고와 같은 웜 블랙(#231f20) 글자, 깊은 소나무 녹색·웜 차콜 패널
   - 유채색 accent는 로즈 하나. 강조 단어·막대·작은 표식에만 쓰고, 주 버튼은 연한 블러시 면 + 먹 테두리
   - 그라디언트 금지(사진 위 글자를 위한 평평한 어둡게 깔기만 쓴다). 모서리는 넉넉하게, 버튼·칩은 알약
   - 장식 도형은 로고의 사각·원 블록만. 앱 목업(.phone)은 실제 앱 색을 그대로 쓴다
   - 다크 모드는 두지 않는다(시스템 설정과 무관하게 항상 라이트) */
