# =============================
# Branch Protection Guidance
# =============================
# To enforce that no one can push directly to 'prerelease' or 'release',
# enable branch protection rules in your GitHub repository settings:
#   - Require a pull request before merging
#   - Require status checks to pass before merging
#   - Require review from code owners (optional, but recommended)
#   - Restrict who can push to matching branches (set to no one)
#
# This ensures all changes to 'prerelease' and 'release' go through PRs and are reviewed/approved by you.
