+// This file stays plain JavaScript on purpose, for three reasons:
+//
+//   1. It can be parsed by ANY Node version, so an operator on an older runtime
+//      gets the message below instead of a syntax error from a .ts file they
+//      cannot execute. The check must run before the import, hence the dynamic
+//      import rather than a static one.
+//   2. systemd, `npm start` and the README all name index.mjs, so nothing about
+//      deployment changes.
+//   3. self-update.mjs sanity-checks that an update archive contains
+//      server/index.mjs before accepting it. Renaming this file outright would
+//      make every legitimate update look malformed.
