# Gates: npm ci (HUSKY=0) -> lint, unit tests, production build (tsc -b inside),
# mocked Playwright e2e. lint/test are independent of build; e2e needs build
# tooling installed but drives its own dev server (playwright.config webServer).
#
# The repo's `verify`/governance script is deliberately NOT run here: it fails
# closed without full git history, and the PR's own CI already runs it — that
# result is ingested into evidence via resolve-pr-head.sh.
