Getting the perfect card

Set <meta name="twitter:card" content="summary_large_image"> to get the big card; without it X may show a bare link.
X falls back to og:title and og:image when twitter:* tags are missing, so fixing og tags fixes X too.
The large card crops to roughly 1.91:1; keep faces and text inside the center of the image.
