While upgrading a project to Tailwind CSS v4, I forgot to remove the
`tailwindcss` import from the PostCSS config. As a result of this, I was
greeted with the following message:
```
node:internal/process/promises:289
triggerUncaughtException(err, true /* fromPromise */);
^
[Failed to load PostCSS config: Failed to load PostCSS config (searchPath: /Users/philipp/dev/project): [TypeError] Invalid PostCSS Plugin found at: plugins[0]
(@/Users/philipp/dev/project/postcss.config.js)
TypeError: Invalid PostCSS Plugin found at: plugins[0]
```
I don't think this was particularly helpful, so I’m proposing we add a
default function export to the `tailwindcss` package so when it's used
inside PostCSS, we can control the error message. So I changed it to
something along these lines:
```
It looks like you're trying to use the \`tailwindcss\` package as a PostCSS plugin. This is no longer possible since Tailwind CSS v4.
If you want to continue to use Tailwind CSS with PostCSS, please install \`@tailwindcss/postcss\` and change your PostCSS config file.

This is also a good place to link to the migration guides once we have
them 🙂
