It looks like this does not work in the standalone CLI, is that expected?

$ NODE_PATH=_build/dev/ npx @tailwindcss/cli --cwd assets/ --config tailwind.config.js -i css/app.css --output ../priv/static/assets/app.css
≈ tailwindcss v4.1.7

Done in 32ms

$ NODE_PATH=_build/dev/ ~/Downloads/tailwindcss-macos-arm64 --cwd assets/ --config tailwind.config.js -i css/app.css --output ../priv/static/assets/app.css
≈ tailwindcss v4.1.7
