Getting the perfect card

Facebook wants og:image at 1200x630 (1.91:1); smaller than 600px wide falls back to a tiny thumbnail.
Facebook caches previews aggressively; after fixing tags, reshare with a query string like ?v=2 to bust it.
og:title around 60 characters survives the two-line clamp in the feed.

Checking another platform? See all previews at once, or fix a missing image with the featured image generator.
