+# Dev Mode support — REQUIRED while Space Settings -> Dev Mode is ON.
+#
+# When Dev Mode is enabled, Hugging Face appends extra build stages to this
+# file and runs these steps INSIDE THIS IMAGE (stage-2 = the image below):
+#     RUN git config --global user.name  "<owner>"
+#     RUN git config --global user.email "<owner>@users.noreply.huggingface.co"
+#     RUN mkdir -p /home/user && ( [ -e /home/user/app ] || ln -s /app/ /home/user/app )
+#     RUN ln -s /dev-mode/init-process /tmp/init-process
+#     LINK COPY --link --from=vscode /opt/openvscode-server /opt/openvscode-server
+#
+# The upstream runtime stage is node:20-bookworm-slim, which ships WITHOUT git.
+# The injected `git config` step therefore died with:
+#     /bin/sh: 1: git: not found        -> exit code 127
+# which failed the whole Space build (BUILD_ERROR / "Job failed with exit code: 1").
+#
+# Installing git here fixes Dev Mode. wget is what the injected OpenVSCode
+# Server stage uses; openssh-client/ca-certificates make the web IDE and SSH
+# usable. Cached layer, harmless when Dev Mode is OFF.
