+# Dockerfile.worker-equivalent
+#
+# Replicates the AWS Deadline Cloud service-managed fleet (SMF) worker AMI
+# environment on top of the base Amazon Linux 2023 image.
+#
+# Use this for building and testing conda packages locally with the same
+# GLIBC version, system libraries, and runtime environment as the real workers.
+#
+# Based on a diff of 768 installed packages on a live SMF worker vs the
+# 289-package AL2023 Minimal AMI baseline (April 2026).
