/* ═══════════════════════════════════════════════════════════════════════════
   토스 스타일 디자인 시스템 — 라이트 모드 · 엔터프라이즈

   토스 디자인의 핵심을 옮겼다:
    · 파랑 하나만 강조색으로 쓰고 나머지는 회색조로 눌러 정보 위계를 만든다
    · 여백을 넉넉히 — 금융 화면은 빽빽할수록 실수가 는다
    · 숫자는 크고 굵게. 사용자가 확인해야 하는 건 결국 금액이다
    · 모서리는 둥글게(12~16px), 그림자는 거의 없이 경계선으로 구분

   외부 폰트·CDN 을 쓰지 않는다. Caddy 가 정적 파일로만 서비스하고
   네트워크 의존을 늘리지 않기 위해서다. Pretendard 가 설치돼 있으면 쓰고,
   없으면 시스템 한글 폰트로 떨어진다.
