The gallery now gets its own origin on the laptop, as it does on the team's server, while the
maps stay on localhost:4610. Chrome and Firefox send any *.localhost name to this computer;
Safari and command-line tools may need `127.0.0.1 research.localhost` in /etc/hosts.
Checked: the tree server answers research.localhost:4610 (gallery 200, with ?tab= and
&lang=ar; manifest 200; the bare root 404, so the address keeps its /index.html).
