+Document T7 changes: mark the TIP-20 reward builders `distribute_reward` and
+`set_reward_recipient` as deprecated (TIP-1075 — post-T7 no-ops). `claim_rewards`
+stays valid: it still checkpoints and settles pre-T7 lazy accruals through T7,
+and pays only already-settled balances from the T8 cleanup fork. Also note the
+dynamic base fee (TIP-1067) so `max_fee_per_gas` should come from a live estimate
+rather than a constant.
