Hi, I’d like to work on issue #316.

I can add tests for "useTheme.ts" covering default theme behavior, toggling, explicit theme setting, localStorage persistence, and the document theme attribute update.

I’ll make sure the localStorage mock is properly reset after each test and that "bun run --cwd apps/web test" passes.
