She set a Schedule (Section 4). Wake: 20°C. Away: 15°C. Home: 21°C. Sleep: 18°C. She locked it with a 4-digit PIN—her birth month and day. Let Leo try his 24°C tyranny now.

Next, she removed the old, yellowed dial thermostat—a relic that clicked with the authority of a grumpy grandparent. Two wires emerged from the wall: a red one labeled R and a white one labeled W .

“Truce?” Leo asked through chattering teeth.

Elara smiled. “Looks like we finally followed the instructions.”
