# Release bcc-ui-theme as a wheel on Hugging Face.
#
# Mirrors biodata-registry/scripts/release.sh, and for the same reasons:
#
#   Why a wheel, not git: HF's git server cannot serve pip's partial clone
#   (--filter=blob:none), so `pip install git+https://huggingface.co/...`
#   fails on a Space build. A wheel over the resolve (HTTPS) URL installs.
#
#   Why git-LFS and not `hf upload`: the HF API token is read-only and returns
#   403 on upload. The wheel ships as an LFS-tracked file committed at the repo
#   root. Each wheel needs its OWN .gitattributes line — the entries are
#   per-filename, not a *.whl glob — or a binary lands in git proper, silently.
#   And the LFS OBJECT must be pushed BEFORE the ref, or the push is rejected
#   with "LFS pointer pointed to a file that does not exist".
#
#   Why one commit: the wheel ships with its own source, so a release commit
#   can never declare a different version than the wheel it carries. That
#   really happened in biodata-registry (83f95f9 carries 0.1.14 while its
#   pyproject reads 0.1.13).
#
# Run after bumping `version` in pyproject.toml. Requires: uv, git-lfs.
