+# exec the long-running server so it replaces this shell as PID 1.
+#
+# This avoids `npm-run-all` keeping idle `npm`/`npm-run-all` parent processes
+# resident for the lifetime of the container (each a full Node VM holding tens
+# of MiB of anonymous memory). `exec` leaves a single `node server.js` process.

+# PATH is extended so check-db.js's `prisma migrate deploy` resolves the prisma
+# CLI from node_modules/.bin the way `npm run` would have injected it.
