-      The overage buffer is <strong>invisible to users</strong>. We advertise X docs/month but only enforce
-      at <strong>X × (1 + buffer%)</strong> docs. For example, a 150-doc/month plan with a 20% buffer
-      enforces at 180 docs. This prevents hard cutoffs at the exact announced limit, giving users a
-      graceful soft landing.
