Open Graph tags present but no Twitter card tag

A Twitter card meta tag (twitter:card) controls how your page link appears when shared on X (formerly Twitter) and in tools that use the Twitter card protocol, such as Slack and Notion unfurls. Without it, your shared links show only a small thumbnail instead of the large, attention-grabbing image preview. Even though X falls back to Open Graph data, the twitter:card tag is still required to trigger the large-image format. Add a twitter:card meta tag (set to summary_large_image for most sites) alongside your existing Open Graph tags. You can also add twitter:title and twitter:description for full control.
