Once the night is over and the photos have finished rolling in, hosts can now download the entire gallery as a single ZIP archive. One click in the host detail page kicks off a server-side stream — files are zipped sequentially and sent down as the archive is built, so memory usage stays bounded no matter how many photos and videos are in the gallery.
Originals only. We keep everything at full resolution, so the archive you get is the archive your guests took — no recompression, no quality loss between scan and send-off.
This is a host-only affordance. The guest-facing gallery and the demo are unchanged.
