Feature Flag Governance

Centralize flag definitions in a frozen enum; expose helpers to set, clear, and target specific audiences.
Test both enabled and disabled states in CI; clean up targeting after each spec to keep shared environments stable.
For LaunchDarkly-style systems, script API helpers to seed variations instead of mutating via UI.
Maintain a checklist for new flags: default state, owners, expiry date, telemetry, rollback plan.
Document flag dependencies in story/PR templates so QA and release reviews know which toggles must flip before launch.
