Coolant lands first: each unit removes 12 heat. Generation follows, then any scheduled surge hits the hottest zone. From Cascade onward, overheated zones also warm their neighbours. The forecast counts every step before you commit.
Hold all zones in band to grow a streak. At 85 heat a zone becomes critical; bringing it directly back into band on the next cycle pays a rescue bonus. Clearing every critical zone restores the frozen streak. Keep this campaign below 85 for Cool Head. Survive all five campaigns to win.
