   legacy-tools.css — 기존 계산기 전용 호환 스타일시트
   --------------------------------------------------------------------------
   ★ 왜 이 파일이 있나
     tools/loss-calculator.html 은 구 사이트의 클래스명(.field .btn .result__row
     …)으로 짜여 있고, 그 안에 검증된 계산 로직이 들어 있습니다.
     HTML 을 손대면 로직을 깨뜨릴 위험이 있어, 구 클래스명을 그대로 살리되
     색만 새 브랜드로 바꾼 스타일시트를 따로 둡니다.

   ★ 충돌 걱정 없음
     새 사이트는 전부 sdc- 접두사를 쓰고, 이 파일은 계산기 페이지에서만
     불러옵니다. 두 이름 공간이 겹치지 않습니다.

   ★ 계산기를 새로 쓰게 되면 이 파일은 삭제하세요.
