test_mixed_zero_nonzero_bytes_floor_cost()

Documentation for tests/amsterdam/eip7981_increase_access_list_cost/test_transaction_validity.py::test_mixed_zero_nonzero_bytes_floor_cost@c74f1a67.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7981_increase_access_list_cost/test_transaction_validity.py::test_mixed_zero_nonzero_bytes_floor_cost --fork Amsterdam

Test floor cost calculation with mixed zero and non-zero bytes.

This ensures floor gas uses floor token counting: - Each data byte contributes 4 floor tokens
