/* 와트 마력 변환기 전용 CSS (2026-10-21). 출력 시험대: [등식 카드 | 들어 올리기] / 전동기 명판 띠 / 자주 찾는 값.
   폭(작업면 컨테이너 whp): 760 이상 [등식 | 들어 올리기](들어 올리기 칸은 등식 카드 높이만큼 늘어남), 그 아래 한 열.
   등식 칸(v2in): 아래 여섯 칸은 2열(3열이면 1,920px에서도 한 자리 긴 341,214.16 Btu/h가 잘림), 360 미만(휴대폰)이면 여덟 칸 모두 '라벨 | 입력' 한 줄씩.
   움직임(R45): 승강기가 1초 동안 오름(linear, 시계 0.0 → 1.0 s), 명판 띠가 값 쪽으로 미끄러짐(0.5s). 동작 줄이기면 둘 다 바로. 공용 부품 assets/v2.css */
