    """Vehicle master for the plating shop's pickup & delivery fleet.

    A vehicle belongs to a facility (its home base), carries insurance,
    registration and service dates, and tracks its current driver and
    state. Vehicles flagged `tdg_certified` are approved to carry TDG
    (Transportation of Dangerous Goods) loads — e.g. stripped parts with
    residue, waste drums, spent chemistry.

    The module works without Odoo's Enterprise Fleet module: all
    fleet-level concerns are modelled here so that CE-only installations
    are fully supported.
