X header size and safe area

The recommended X (formerly Twitter) header is 1500 × 500 pixels, a 3:1 ratio, under 5 MB. Your profile picture overlaps the lower left, and the top and bottom are cropped a little on some screens, so keep key details in the middle band. For in-feed images, use the 1600 × 900 post preset.
