Struct TailwindDarkModeRule 

pub struct TailwindDarkModeRule { /* private fields */ }

Enforces that hardcoded Tailwind color utilities always have a dark: counterpart.

For example, className="bg-white text-black" will be flagged because there are no dark:bg-* or dark:text-* variants present. shadcn semantic token classes like bg-background and text-foreground are allowed by default because they resolve via CSS variables that already handle both themes.

This rule scans JSX/TSX/HTML files for class attributes and analyzes the Tailwind classes within them.
