{# Self-canonical. For ?page=N listings (paginated kind/manufacturer/
geo pages) we keep the `?page=N` query param so each pagination
page indexes as its own URL — stripping it would tell Google
page 2 = page 1, collapsing the entire pagination chain back to
page 1 and re-orphaning every car only reachable past page 1.

§ C1. All other query params (?ref=, ?from=, ?sort=, etc.) are
UI state and intentionally NOT in the canonical. #}

# init. crossorigin needed on pagead2 because the AdSense scripts load
