   pillars on each side. object-fit only sizes the whole frame — it can't
   skip the black inside it — so we crop it ourselves: the sharp video sits
   in a square box (object-fit: cover on a 1:1 box crops exactly the
   pillars, with zero stretching since it's a crop, not an upscale), and
   its own edges fade to transparent via a radial mask so the cut isn't a
   hard square line. A second, blurred+enlarged copy fills the space
   around it so the transition dissolves into a soft glow — same trick as
   Spotify/YouTube letterboxing. */
