10. A method of operating a cooktop appliance, the cooktop appliance comprising a first burner in fluid communication with a first control valve and a second burner in fluid communication with a second control valve, the second burner being spaced apart from the first burner and the second control valve being disposed along a parallel flow to the first control valve, the method comprising:

receiving a single-burner mode command from a user interface;

independently positioning one of the first control valve and the second control valve based on the received single-burner mode command;

receiving a multi-burner mode command from the user interface; and

cooperatively positioning the first control valve and the second control valve based on the received multi-burner mode command,

wherein cooperatively positioning the first control valve and the second control valve comprises

positioning the first control valve based on a directed heat output at the first burner, and

positioning the second control valve based on a directed heat output at the second burner that is equal to the directed heat output at the first burner.

11. The method of claim 10 , wherein the first burner defines a first output diameter, and wherein the second burner defines a second output diameter, the first output diameter being equal to the second output diameter.

12. The method of claim 10 , wherein the first burner defines a first output diameter, and wherein the second burner defines a second output diameter, the first output diameter being larger than to the second output diameter.

13. The method of claim 10 , wherein independently positioning at least one of the first control valve and the second control valve comprises maintaining the at least one of the first control valve and the second control valve below a singular maximum output limit, and wherein cooperatively positioning the first control valve and the second control valve comprises maintaining each of the first control valve and the second control valve below a dual maximum output limit that is lower than the singular maximum output limit.

14. The method of claim 10 , wherein the single-burner mode command is a first single-burner mode command, wherein independently positioning at least one of the first control valve and the second control valve comprises independently positioning the first control valve based on the first single-burner mode command, and wherein the method further comprises

receiving a second single-burner mode command; and

independently positioning the second control valve based on the received second single-burner mode command.

15. The method of claim 14 , wherein the user interface is a first control input, and wherein the second-burner mode command is received at a second control input.

16. A cooktop appliance comprising:

a panel comprising a top surface and a bottom surface;

a first burner assembly comprising a first burner extending at least partially above the top surface of the panel;

a second burner assembly spaced apart from the first burner assembly on the panel, the second burner assembly comprising a second burner extending at least partially above the top surface of the panel;

a first control valve in fluid communication with the first burner assembly to selectively direct a flow of gas thereto;

a second control valve in fluid communication with the second burner assembly to selectively direct a flow of gas thereto; and
