/* style.css — 1021210 DYNAMIC_VISION (동체시력 테스트)
   2026-09-26 REDESIGN: kit-blueprint(헤어라인 계측기) → kit-swiss "육상 경기 포스터"
   - 큰 압축 산세리프(Archivo wdth 62–125 · 800~900) · 두꺼운 잉크 괘선(3·6px) · 12단 비대칭 격자 · 모서리 0
   - 무채 잉크 1색 + 회색 면(--fill) — 유채 액센트·배경 패턴·그림자·그라디언트·블러 없음
   - 테스트 표시 영역(stage/canvas)의 크기 규칙은 구판 그대로(너비 = 본문 폭, 높이 clamp 200–300px) — 노출 시간·KVA 최대 크기가 여기에 달려 있다
   - 자극 숫자 글꼴(JetBrains Mono 700)은 측정 조건이라 유지, UI 에서는 모노 글꼴을 쓰지 않는다 */
