"""Shared pytest fixtures for mgf-vm-firecracker.

Per TESTING.md:
  * tier 1 (unit) — pure functions only; VmSpec→Firecracker JSON
    translation, error mapping. No Firecracker daemon.
  * tier 2 (integration) — against real Firecracker + jailer in a
    container. Opt in with ``-m integration``.

The conformance suite runs at tier 2 against the same containerized
Firecracker, importing ``mgf.vm.core.conformance`` (when it lands).
