CLI Version 4.1.17 hangs when using `--output /dev/stdout`

[argmaxmax]

What version of Tailwind CSS are you using?
v4.1.17

What build tool (or framework if it abstracts the build tool) are you using?
None, just the cli tool on linux

What operating system are you using?
NixOS (Linux)

Reproduction URL

this works/completes:

tailwindcss --output -

This just hangs:

tailwindcss --output /dev/stdout

Describe your issue

It should be functionally the same, /dev/stdout is a perfectly normal linux file for writing to, but tailwindcss just hangs.
