X (Twitter) Card Not Showing? summary vs summary_large_image, Fallbacks, and the Checks That Actually Matter

Proof Over Promises.
The note that no Open Graph tag selects the large card clears up a lot. People add og:type="article" and expect the wide image, but without twitter:card set to summary_large_image it never shows. With the Card Validator gone since 2022, a short troubleshooting order like this is genuinely handy.
