- Split renderProbeCards into createProbeCards (once) and updateProbeCards (mutates only the values: name, target, temp, status, dot color). - Skip refreshing setpoint input values while a field has focus so typing is not interrupted by the 5s poll. - Stop calling refreshDashboard after saveSetpoint to avoid clobbering input.
