summary vs summary_large_image?

Summary cards use a small thumbnail next to text. summary_large_image uses a large hero image on top — usually higher engagement.

The HTML meta tag namespace is still "twitter:" for backwards compatibility, even after the rebrand to X.

X caches OG data aggressively. After updating, validate with the X Card Validator to force a refresh.
