+<!--
+  Default splash: served by HAProxy itself (`http-request return ... file`,
+  hap_listener.tpl) for any request whose Host is not routed to a site --
+  the server's own hostname, a bare IP, an unconfigured name. Static on
+  purpose: no version, no hostname echo, no customer data, no links (in
+  particular none into the control panel). Loaded with `file`, not
+  `lf-file`, so `%` is literal here and nothing from the request is
+  expanded into it. Must stay well under tune.bufsize (16 KB) or HAProxy
+  rejects the config.
