Summary

I'm trying to include a .streamlit directory in my source distribution and wheel. It lives next to my pyproject.toml.

Partial pyproject.toml:

[tool.uv]
package = true

[tool.uv.build-backend.data]
data = ".streamlit"

However, when running uv build, this directory does not appear in the output, and is not included in the source distribution or wheel.

Am I misunderstanding the documentation or is this a bug?
