Header

Generate a solid-color Twitter/X banner PNG from a hex color.

The generated banner is 1500x500, which matches the recommended Twitter/X header image size.

Usage

Generate a banner at the default output path:

mix header.generate "#1DA1F2"

This writes:

output/twitter_header_1DA1F2.png

You can also provide a custom output path:

mix header.generate ff8800 output/orange_header.png

Hex colors must be 6 digits. The leading # is optional. Default filenames use the normalized uppercase hex value.
