   1) JS 가 클릭 좌표(--reveal-x, --reveal-y) 와 화면 대각선(--reveal-max) 를 root 에 세팅
   2) startViewTransition() 호출 → DOM 캡처 → 새 root 의 dark/light 클래스 swap
   3) ::view-transition-new(root) 가 mask-image radial-gradient 로 노출
   4) @property 로 length 등록된 --reveal-radius 를 0 → --reveal-max 까지 보간 →
      안쪽 50% 는 solid, 바깥은 transparent 로 페이드되는 부드러운 가장자리가 퍼짐

   미지원 브라우저(Firefox 등)는 이 셀렉터가 무시되므로 즉시 swap. */
