27 lines to 11. What went: the measured deny line (it is in the PR and the
commit that made the change), the "one value, two readers" argument for reading
the option the target URL is built from, and a note about `unique`.
What stayed is the part nobody can re-derive from the code: `external` must not
be dropped, both hyperhive hosts are private addresses the builtin denies, and
the entry is deliberately not gated on the per-host `deploy.swarm-ui.enable`
because a spread deployment has the forge and the swarm host on different
machines.
