Documentation for tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists_eip4895.py::test_bal_withdrawal_and_transaction@892e6d1e.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists_eip4895.py::test_bal_withdrawal_and_transaction --fork Amsterdam

Ensure BAL captures both transaction and withdrawal balance changes.
