edit_video gains an overlay step that lays a PNG, JPEG or WebP image over the
video at a corner or the center, sized to a share of the frame width, with
optional opacity and time range; tall frames keep the 9:16 safe areas clear.
concat takes at: "start" so an intro can go before the video. The image is
authorized like other inputs, read with its own demuxer and refused above
8192 pixels on a side. New Studio specialists are told to brand with the
user's logo and intro.
