+# Builds both the default and aws-feature omnigraph-server images and pushes
+# them to ECR. Invoked manually via workflow_dispatch — not wired to tags or
+# main pushes today.
+#
+# Prerequisites:
+#   - Repo vars AWS_REGION, AWS_ROLE_TO_ASSUME, AWS_CODEBUILD_PACKAGE_PROJECT,
+#     AWS_ARTIFACT_BUCKET are set.
+#   - The shared workflow at ModernRelay/.github supports the `features` and
+#     `image_tag_suffix` inputs (ModernRelay/.github PR #2 or later).
+#
+# Each invocation produces two ECR tags per source commit:
+#   - <source_sha>         (default features)
+#   - <source_sha>-aws     (--features aws)
