/* Heatwise — urban heat mitigation console.

   Design rules this file holds to (redesign brief §13–§16):
   - one restrained accent; amber/red/green mean something, they are not decor
   - the temperature ramp is data, and never appears in the chrome
   - borders and spacing carry hierarchy; there are no shadows and no glow
   - radii are 3–6px, never pill-shaped panels
   - transitions are 150–200ms and only on state changes a user caused */
