In @components/pagination.tsx:
- Line 147: The className string in the pagination component contains a
concatenated class token ("dark:bg-gray-900text-gray-400") causing a CSS syntax
error; edit the className (the disabled control or button element where
className is set in components/pagination.tsx) and insert a space between
"dark:bg-gray-900" and "text-gray-400" so the two Tailwind classes are separate
and apply correctly.

Critical: Missing space between CSS classes.
Line 147 has a syntax error where two classes are concatenated without a space: dark:bg-gray-900text-gray-400. This will cause the classes to not be applied correctly.

Critical: Potential hydration mismatch and missing state persistence.
The theme state is hardcoded to true without checking the actual DOM state on mount. This creates several issues:
- Hydration mismatch: The initial state may not match the server-rendered HTML, causing React hydration errors in Next.js
- Lost state on reload: Theme preference doesn't persist across page refreshes
- Incorrect initial render: If a user previously selected light mode, the component will incorrectly show dark mode icons on first render
