name: Deploy to GitHub Pages

# Legacy branch-based Pages builds stalled on this repo (stuck rebuilding an old
# commit and never advancing to main's tip). This Actions-based deploy publishes
# the repo root on every push to main — reliable and re-runnable via the Actions
# tab. The CNAME file in the repo root preserves the bauhaus.such.software domain.
