+title: Improve `charge_transaction_payment benchmark` ergonomics
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      Adds a `setup_benchmark_environment()` hook to allow runtimes to configure
+      required state before running the benchmark (e.g., setting block author for
+      fee distribution). Also fixes `amount_to_endow` calculation to use actual
+      computed fee and ensure it meets the existential deposit.
