What happens if the car is worth more than the residual at lease end?

If the car's market value exceeds the residual value when your lease ends, you have positive equity. You can buy the car at the residual price (which is below market value) and either keep it or sell it for a profit. This happened frequently during the 2021-2023 used car market spike and can still occur with high-demand vehicles. It is one of the underappreciated benefits of leasing a car that holds its value well.
