  "rationale": "Stormheart-violet panels make the interface read as a charged weather instrument rather than neutral administration. Lightning-white text and high-sky blue secondary lettering remain clear through the dark field, while sunwell-gold focus and primary controls resemble captured radiance. Pale cloudstone buttons, doubled glass-like panel borders, rounded oval corners and small hard shadows translate the city’s vaults, prism screens and visibly repaired apparatus without disturbing familiar information hierarchy. Broad humanist headings feel civic and optimistic; compact monospaced numbers keep sunshine, rainwater, Static and thunderbolt counts steady during a busy weather cycle. Warnings pair lightning-white language with explicit status symbols so danger never depends on colour alone.",
