Admins can now disable specific AI features per tier from Admin > Tier Limits — new feature_flags table (feature x tier -> enabled, defaulting to true so adding a new gated feature never needs a backfill). Covers recipe variations, drink pairing, and meal pairing to start. When disabled for a user's tier, the button stays visible (with a small lock badge) but opens an upgrade dialog instead of running; the API route rejects the call server-side either way (requireFeatureEnabled, re-reads tier from the DB rather than trusting the session's cache, same rationale as checkAndIncrementTierLimit). The upgrade dialog is informational only — no Stripe checkout exists yet (STRIPE_PLAN.md is still just a plan) — its CTA links to /support prefilled as an upgrade-interest suggestion.
