  /* object-fit: cover forced this landscape (1920x1066) video to fill a
     tall portrait box, cropping hard and leaving only the center visible —
     switched to contain below so the whole frame shows, letterboxed
     against the starfield canvas behind it. Contain on a portrait box is
     always width-constrained here (video render height 1920:1066 of the
     full viewport width is far shorter than any phone's viewport height),
     so the rendered strip is exactly 100vw wide by ~55.52vw tall
     (1066/1920), vertically centered in the 100svh box. Left stays the
     desktop x% — width isn't cropped in this framing, only letterboxed
     top/bottom — but top is recomputed from box-relative % to
     strip-relative %: 50svh + (desktop-top% - 50%) * 55.52vw. */
