LGTM, thank you!

Actually, npm run build fails with

./src/app/styles/themeContext.tsx:26:42
Type error: Argument of type '"light" | "dark"' is not assignable to parameter of type '"light"'.
  Type '"dark"' is not assignable to type '"light"'.

  24 | export const ThemeModeProvider = ({ children }: { children: ReactNode }) => {
  25 |     const [mode, setMode] = useState<'light' | 'dark'>('light');
> 26 |     const theme = useMemo(() => getTheme(mode), [mode]);
     |                                          ^
  27 |   
  28 |     const toggleTheme = () => {
  29 |       setMode((prevMode) => (prevMode === 'light' ? 'dark' : 'light'));

maybe the dark theme related stuff needs to be deleted?
