## Summary
Inspired by #19460, relaxes whitespace syntax around `@source
inline(…):`
### Before
```css
/* ❌ Error: `@source` paths must be quoted. */
@source inline( "underline" );
@source inline(
"underline"
);
```
### After
```css
/* ✅ Generates the class names as normal. */
@source inline( "underline" );
@source inline(
"underline"
);
```
## Test plan
Added tests to `packages/tailwindcss/src/index.test.ts`.
