tailwind-cli casually emits to stderr

eprintln(header())

when using a tool like process-compose and others such executioners this causes the process to immediately exit even if the --watch option is passed. This should not be emitted to the error channel to begin with, it denotes a success

Hi! This is intentional and follows the standard conventions around how CLI tools are built.

This is common misconception. Per the POSIX standard stderr is not strictly for errors. It's meant to be used for any diagnostic output. This includes things like human readable output, user-interactive prompts (several shells do this), information messages, warnings, errors, progress reporting (e.g. this is what curl does). Generally stdout should be used for things you'd want to pipe to either a file or another program.
