스크롤만으로 장면을 여는 CSS 항해
-- JavaScript 없이 sticky layout, scroll snap, view timeline, mask를 조합해 밝고 읽기 쉬운 - 인터랙티브 랜딩 페이지를 실험합니다. -

+ CSS scroll-driven narrative
+CSS로 이어지는 네 장면
++ 스크롤 위치를 장면의 시간축으로 삼아 신호부터 읽기 fallback까지 연결합니다. 모든 흐름은 + HTML과 CSS만으로 작동합니다. +

신호 수집
-view timeline이 지원되는 브라우저에서는 카드가 viewport 진입률에 맞춰 또렷해집니다.

+신호를 포착하다
++ 첫 장면이 viewport에 들어오면 view timeline이 원의 간격과 신호점의 농도를 조절합니다. + 지원하지 않는 환경에서는 완성된 정적 지도가 그대로 보입니다. +
+-
+
- 텍스트와 시각 효과를 독립적으로 유지 +
- 장면 진입률은 CSS timeline으로만 계산 +

궤도 이동

+궤도를 따라 이동하다
++ sticky 장면 안에서 항해점이 경로를 따라 이동합니다. 페이지 스크롤은 브라우저가 그대로 + 소유하며, 별도의 scroll hijacking은 없습니다. +
+-

- scroll snap은 가까운 장면 정렬만 보조 +
- 키보드와 anchor 이동 순서를 그대로 보존 +

+하나의 지점에 도착하다
++ 여러 궤도가 한 좌표로 수렴하면서 앞선 장면의 흐름을 정리합니다. 진행 표시줄은 전체 + 문서에서 현재 위치를 계속 보여 줍니다. +
+-
+
- 전체 진행률과 장면 번호를 함께 제공 +
- 색상 외에도 선, 크기, 문장으로 상태 전달 +

읽기 유지
-- scroll-driven animation이 꺼져도 장면 순서와 문장이 그대로 남아 여정을 끝까지 읽을 수 - 있습니다. -

-
- 모션은 기능 향상으로만 적용 -
- 정적 환경에서도 모든 장면 유지 -
