+# Without this, HTTPS on a Moshpit name cannot work. No public CA will ever sign
+# for `.eggs`, so a name answers its origin's own self-signed leaf and a stock
+# client refuses it — correctly. moshpit-proxy generates one local root and
+# terminates TLS in the one language a browser accepts, which turns "trust this
+# certificate" from a thing you do per name into a thing you do once.
+#
+# Installed here rather than left as a follow-up step because the alternative is
+# `moshcode dns enable` finishing successfully, every name resolving, and every
+# https:// URL still failing — which reads as broken, not as unfinished.
+#
+# This is the one part of the install that touches the system's trust store, so
+# it is the one part with an opt-out: MOSHCODE_NO_PROXY=1 skips it entirely, and
+# `moshpit-proxy install.sh --uninstall` undoes it later. It installs no DNS
+# routing and starts no resolver -- `moshcode dns enable` stays a thing a person
