Hreflang set missing x-default

MediumNeeds reviewInternationalizationPer-page checkhreflang_no_self_reference

What this means

The page declares hreflang alternates but none of them is x-default, so there is no declared fallback for visitors whose language and region match no listed version.

How to fix it

Add an x-default hreflang entry pointing at the version that should serve everyone else.

Fix effort

This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
