/* =========================================
   F1 피트스톱 & 레이스 전략 가이드 (strategy.css)
   templates/guide/strategy.html 전용

   guide.css의 공통 레이아웃(.guide-page / .guide-back-btn / .guide-page-title)에 더해
   이 페이지 전용 섹션 내비게이터·비교 카드·스테퍼·피트 윈도우 타임라인·
   전략 대시보드 스타일만 정의한다.

   팔레트는 사이트 공통값을 따른다:
     배경 #0a0a0a / #111 / #1a1a1a, 보더 #2a2a2a, 액센트 #dc2626
   모든 시각화는 이미지 에셋 없이 CSS + 이모지로만 처리한다(신규 JS 없음).
   상태·성격 구분은 색상 단독이 아니라 항상 텍스트 라벨과 병행한다.
