My assessment

getUserInitials, isActive, formatAccountDate, and formatAccountId are utility logic mixed into the UI file. They should live in a shared utils file. useMemo is being used for simple filtering. That is not wrong, but it adds extra reading cost here. Plain variables would be simpler. The main render block is too long because it includes both navigation links and footer account actions. The category dropdown branch inside map() makes the middle of the component harder to follow. Auth actions and signed-in footer are mixed together with general menu rendering. This file repeats logic that should probably be shared with desktop navbar, especially getUserInitials and isActive.
