   into a fixed 180px-tall strip instead of scaling with width -- this is "can't see the live
   image on a smartphone" (2026-09-01): the box was there, just too short and warped to aim a
   phone camera with. height: auto (no forced aspect-ratio) lets it scale by its own intrinsic
   ratio instead, whatever the camera actually negotiates (qr_scan.js requests 16:9, but that's
   only a hint the browser/camera can still ignore) -- this only resizes the on-screen box; the
   decode itself reads the camera's native videoWidth/videoHeight via canvas either way, so this

   preview reads as the page's focal point on desktop instead of a small corner element; the
