Subject: [PATCH] part: surface the functional mixed-signal model separately
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `spice` field on a digital part is a power and loading macromodel — it draws
the right quiescent current and cannot shift a bit. Showing it under a single
"SPICE model" heading implies the part is simulatable, which for the digital
parts it was not.

`spice_mixed` is a model that performs the part's actual function, verified by
simulation, and it is now shown as its own section with what was verified and
what is not modelled. The download bundles both, so a deck gets the functional
model and keeps the supply behaviour.
