name: Deploy to Pages

# Builds the app and publishes it as this repository's site.
#
# midiboot imports the simulated instruments as source from the sibling
# repos (simulated_instruments/<repo>/instrument), so the job recreates
# the vault layout inside the workspace: this repository is checked out
# at proof-of-concept/midiboot and each instrument repo at
# simulated_instruments/<repo>, which is where the relative imports and
# vite's fs.allow expect them. The instrument checkouts pin ref: main
# (without it, checkout would ask the sibling for this repository's
# commit sha), so the deployed site tracks the siblings' main as of the
# time this workflow runs; a push to a sibling does not retrigger it.
#
# Three 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.
#   - the runner is one small machine shared by every repository in the vault,
#     so this workflow does no more than install, build, and publish. The tests
#     are deliberately not here: run `npm test` locally, and the per-model
#     checks in each simulated_instruments/<repo>/instrument, before pushing.
