Twitter Cards

Handles Twitter Card meta tags so your links look good when shared on X. You get the four card types (summary, summary_large_image, app, player), recommended image specs (1200×675px, under 5MB), and implementation examples for Next.js and plain HTML. It reminds you that Twitter falls back to Open Graph tags if you skip the twitter:card tags, which is why most people add both. The validator link is handy for testing before you ship. One thing to note: it correctly treats Twitter Cards as purely about link previews, not about crafting the actual post copy, which matters when you're thinking about your sharing strategy.
