name: Enterprise E2E (Playwright)

# Enterprise Playwright suite — exercises premium-key gated features (audit,
# teams, analytics) plus full OAuth + SAML logins via the Keycloak compose
# stacks under testing/compose. Slow and secret-gated, so it runs in three
# situations:
#
#   - PRs that touch proprietary / premium / SSO compose / enterprise tests
#     (driven by build.yml via workflow_call, path-filtered against
#     .github/config/.files.yaml `proprietary`),
#   - every push to main (post-merge safety net),
#   - on a nightly cron schedule (catches Keycloak image drift, license
#     expiry, upstream proprietary changes),
#   - manual workflow_dispatch.
#
# Auto-skipped when secrets.PREMIUM_KEY_ENTERPRISE is missing (forks, dependabot).
