name: Deploy to Pages

# Builds webapp/ and publishes it as this repository's site.
#
# Two notes on the vault:
#   - there is no cache service, so setup-node runs without `cache: npm`;
#   - a mochi site is served at /<collection>/<repo>/site/ or at the root of an
#     origin of its own. The Vite build uses a relative base (`base: './'`), so
#     it works at either without being told the deploy path, and configure-pages
#     is therefore only here for parity with the deploy step.
