/* 디제틱 미세 애니 v2 — 씬의 키 라이트가 만든 것만 움직인다 (CANON-3 §3).
 *
 * 왜 CSS 인가
 * -----------
 * 기존 움직임은 `E-*.webp` 를 WebGL 워프로 흔드는 방식이었고, 그 요소들은 **옛 그림에서**
 * 오려낸 것이라 새 배경 위에서는 남의 물건이다(설치 때 `_bgv2-retired-*` 로 뺐다).
 * 새 그림은 광원을 그림 안에 그려서 왔으므로, 움직여야 하는 것은 **그 광원의 숨**이다.
 *
 * 규율 (전부 실측 근거)
 * - `transform` · `opacity` 만 쓴다. 프레임마다 `filter`/`backdrop-filter` 를 바꾸지 않는다
 *   (iOS Safari 프레임 낙차). SVG 필터 애니 금지 — traps #2.
 * - 주기 2.4s 이상(불꽃만 1.4s), 진폭은 화면 대각의 1.5% 이하. "봤다"가 아니라 "숨쉰다".
 * - 깊이가 둘이면 **원경이 더 느리고 진폭이 작다**(steam-spaceunbound-1 실측).
 * - `prefers-reduced-motion: reduce` 에서 이동·흔들림은 정지. 밝기 호흡은 산다.
 * - 좌표는 **390x844 실기 프레임에서 눈으로 잡은 뷰포트 비율**이다.
 *   배경은 `object-fit: cover` 라 plate 좌우 각 15.3%가 잘린다 — plate 좌표를 그대로 쓰면 어긋난다.
