45-55: Consider harmonizing icon sizing/spacing in the radio items.

The trigger uses a fixed icon size, while the menu items currently render icons without sizing or spacing classes. Consistent sizing avoids visual jumps.

♻️ Suggested tweak

-            <SunIcon />

Document or remove the unused getTheme prop, and clarify its contract.

The optional getTheme parameter is never used in the codebase but could easily be misused if provided. If a caller passes a function returning a resolved theme (light/dark) instead of the user's selection (which could be "system"), the icon and radio group will display incorrect state. Either add inline documentation specifying that getTheme() must return the user-selected theme including "system", or remove the parameter if it's not needed.
