"""Coerce source-DB values into types ``sqlite3`` can bind.

pyodbc returns ``NUMERIC``/``DECIMAL``/``MONEY`` as :class:`decimal.Decimal` and
date/time columns as :mod:`datetime` objects, none of which ``sqlite3`` binds
natively. Cache columns are ``TEXT``, so stringifying is lossless and consistent
with how the data is stored. This is done **locally** — never via a global
``sqlite3.register_adapter`` — so the host application's ``sqlite3`` behaviour is
left untouched.
