/* ============================================================================
   SHORTHAND 공부방 — 전면 리디자인 v1 (20260704)
   컨셉: 계측기(measurement instrument).
   - 숫자(속도·정확도)는 Space Grotesk 탭룰러로 세워 계기판처럼 읽히게 한다.
   - 시그니처: 진도 사다리(goal-ladder). 110→170 단계가 페이지의 정신 모델이므로
     통과/현재/잠김 상태 언어를 사다리에서 파생시켜 전체에 일관 적용한다.
   - 강조 규율: 채운 보라 버튼은 화면당 1개(주 CTA). 완료 상태의 목표 CTA는
     잉크색 채움으로 구분해 강조 충돌을 없앤다.
