* labware.mt_quantos_qh016_bnmw - QH016-BNMW powder dosing head: geometry REUSED from the mt_quantos_q2 instrument asset's
`dosing_head` part (mesh objects + collision proxies), re-based to the outlet tip; real model data from the Quantos operating
instructions (p.102 technical data, p.107 part number, p.21 installation, p.29 filling, p.94 storage).
* labware.mt_quantos_head_container - the plastic container each head is delivered and stored in (manual p.27, p.94); used as the
head's holder on the bench shelf (Mettler lists no head rack among the Quantos accessories, manual p.107-110).
* target vial: the Agilent 20 mL screw-top vial already in the catalog (real model, fits the Quantos sample-container limits of
manual p.103); the instrument asset's `sample_container` part is an authored placeholder (its contract says the size is not a
maker dimension), so it is not exported as a type.
Fit checks against the instrument asset (head_slot, container seat, powder outlet) are computed here and stored in
labware.instrument_fit; tests/test_labware_assets.py asserts them.
