README, SPEC and docs no longer present traefik as the required front
proxy, and call it the TLS-terminating proxy. The README section of that
name lists what the proxy must do: forward plain HTTP to port 8080, keep
Host, set X-Forwarded-For and X-Forwarded-Proto, close an unused
connection in under 120 seconds, and connect from an address in
SWW_RPROXY_TRUSTED_PROXIES. traefik, Caddy and nginx appear as examples,
with the Caddy and nginx settings their defaults lack.
