name: Browser suite

# The per-push CI gate deliberately skips the Playwright-driven suite (config/test-suites.ts),
# so a browser-only regression can merge green. This job runs that suite on a schedule and on
# demand, so such a regression (the Shift+Enter keypress bug was one) is caught within a day
# instead of by a user. It is NOT a merge gate: a red run means "look", and it never blocks a
# push or a PR.
#
# Needs: chromium (installed below), tmux, and the live server the tests start themselves.
# Not run here: test:mobile (per-machine PNG baselines), test:perf (wall-clock), and
# codex-predictive-echo (needs a real codex binary; it also skips itself without one).
