 temporary filesystems. The broker trusts proxy headers because Nginx is its
 only production ingress; Nginx replaces rather than appends client-supplied
 forwarding headers.

+streams pass directly between clients and Gitea. The Nginx cache tmpfs remains
+available for other proxy activity and is sized above typical repository pack
+files.
