+### Feature Gating Rules
+
+- Never check `user.isVip` or `plan == UserPlan.vip` directly in widgets or screens
+- All access control goes through `featureFlagsProvider` — read the relevant flag, wrap with `PaywallGuard`
+- Quantity limits (e.g. max accounts) are enforced inside repositories, not in widgets — throw `FeatureLimitException` on violation
+- Routes that are entirely VIP-only use GoRouter `redirect` reading `featureFlagsProvider`
+- Adding a new gated feature means: add a getter to `FeatureFlags`, implement in `FreeFeatureFlags` and `VipFeatureFlags`, then use in UI/repo
