# Deploy the static site in /docs to GitHub Pages.
#
# Replaces the legacy "Deploy from a branch" (Jekyll) build, which ran on
# EVERY push to main and failed because Jekyll's Liquid parser choked on the
# planning docs under /docs (e.g. `Unknown tag 'data'` in EVALUATION_PLAN.md).
# /docs is a hand-written static site (index.html + robots/sitemap/llms.txt),
# so we upload it as-is — no Jekyll — and only run when the site changes.
#
# Requires the repo Pages source to be set to "GitHub Actions"
# (Settings → Pages → Build and deployment → Source: GitHub Actions).
