"""Back-compat shim — moved to :mod:`vibeqc.smearing` in v0.10.0.

Every public symbol that lived in ``vibeqc.occupations`` continues
to import from here, so existing user code and downstream tests
keep working without edits. The shim emits no warning on import
(too noisy for a module that's loaded eagerly by the periodic SCF
drivers) — the user-visible deprecation surface lives at the
``smearing_temperature=`` kwarg level on the high-level wrappers
and on the C++-bound options structs.

Removal target: v0.11.0, alongside removal of the legacy
``smearing_temperature: float`` field on the periodic options
structs. See `docs/design_smearing.md` § Q4 for the schedule.
