Analysis
fly.io's social meta tag setup passes every check we run. The required tags are present, the image is well-sized, and the title and description fit comfortably within Twitter / X's truncation limits. There's not much to improve here - this is a strong reference for anyone looking to optimize their own social previews.
What's working well: social share image found; title length is good (36 chars); twitter card type: summary_large_image. 3 of the checks we run pass cleanly.
