The library is focused on text styling so it only implements ANSI SGR parameters. I used this as a reference:
https://en.wikipedia.org/wiki/ANSI_escape_code
The full list of supported SGR parameters is in the README: https://github.com/kubetail-org/fancy-ansi?tab=readme-ov-fil...
Let me know if you have any suggestions on how to make it clearer which subset of ANSI is supported.
