# vfrplan agent — Docker Space.
#
# Replaces the earlier Gradio SDK version of this same Space. Switching SDK is
# a README.md metadata change (sdk: gradio -> sdk: docker) plus this file; see
# DEPLOY.md §1 before the first push, because leaving the old metadata in place
# makes the Space ignore this Dockerfile entirely.

# git/git-lfs/curl/wget/procps are not used by the app. They are what Hugging
# Face's Dev Mode layer needs (VS Code in the browser + SSH); without them a
# Space with Dev Mode enabled fails to build with a bare "git: not found",
# which is exactly how the vfrplan-mcp Space failed on its first deploy.
