+# Makima Daemon - Lightweight Container Image
+# ==============================================================================
+# This Dockerfile builds a minimal image for running `makima daemon` in
+# Kubernetes. Unlike the full server image (which includes ML models), this
+# image contains only the makima binary and the tools it needs to execute
+# tasks: git, gh CLI, curl, and SSH client.
