shadcn-ui/lint's `parseDeclarations` function, specifically its CSS comment stripping regex and its impact on theme parsing and the `no-arbitrary-values` rule.

## Summary

`parseDeclarations` strips CSS comments with `css.replace(/\/\*[\s\S]*?\*\//g, "")` before scanning for `--*` declarations. That regex does not know about string literals, so the `/*` inside a Tailwind `@source` glob such as

```css
@source "../node_modules/streamdown/dist/*.js";
```

is treated as a comment opener. Everything up to the next real `*/` in the file is discarded, which in a typical `globals.css` means the `@theme inline { … }` block and the `:root { --radius: … }` declaration.

The theme then silently falls back to Tailwind's default scale, and `no-arbitrary-values` reports *exact* replacements that are wrong for the project. Applying them via `--fix-suggestions` changes rendered output.

The `@source` line above is the one [streamdown's README](github.com/vercel/streamdown tells every user to add, so this is likely to hit anyone using it with a `calc(var(--radius) …)` ladder.

## Reproduction

`app/globals.css`:

```css
@import "tailwindcss";
@source "../node_modules/some-pkg/dist/*.js";

@theme inline {
--radius-sm: calc(var(--radius) - 4px);
--radius-md: calc(var(--radius) - 2px);
--radius-lg: var(--radius);
--radius-xl: calc(var(--radius) + 4px);
}

:root {
--radius: 0.375rem; /* 6px */
}
```

`page.tsx`:

```tsx
export default function P() {
return ;
}
```

With `"shadcn/no-arbitrary-values": "error"`:
