Documentation for tests/cancun/eip4844_blobs/test_excess_blob_gas_fork_transition.py::test_fork_transition_excess_blob_gas_post_blob_genesis@88e9fb8f.

Generate fixtures for these test cases for Osaka with:

fill -v tests/cancun/eip4844_blobs/test_excess_blob_gas_fork_transition.py::test_fork_transition_excess_blob_gas_post_blob_genesis --fork Osaka

Test excessBlobGas calculation in the header when the fork is activated.
