Question 1

Does wikipedia.org declare image dimensions?

wikipedia.org sets `og:image` but does not include `og:image:width` and `og:image:height`. Explicit dimensions let platforms render the preview faster without downloading the image first.

wikipedia.org's social headline is "Wikipedia, the free encyclopedia" (32 characters).

Question 3

Missing twitter:card tag. Without this, Twitter may not show a preview card at all.
