"""Parity contract between the OWL JobFacetedFilters component
(origin) and the widget's SSR faceted-filters template (widget).

The two implementations render the SAME visual UI from the SAME ES data
but live in two engines (OWL XML for origin, QWeb for the widget). Until
one is migrated to consume the other, we pin the **visible class set**
and **JS hook selectors** that both must expose so a designer's change
to one side fails CI loudly instead of silently diverging.

This test reads the source files (not the rendered output) so it stays
fast and catches changes at the template level.

When the two are eventually consolidated (G2 in the gap analysis), this
test can be removed.
