# Stage rustdoc artifacts for Sphinx documentation build

# This script copies the generated rustdoc output from target/doc/
# to docs/_static/rustdoc/ so it can be included in the Sphinx build.

# Usage: ./scripts/stage-rustdoc.sh
#
# Prerequisites:
#   - Run `cargo doc --no-deps --all-features` first
#   - target/doc/ must exist with generated documentation
