* One frame of tilt. With a ground pivot the camera swings about it (lookAt),

* regional range is several degrees steeper than the pivot's (the Earth
* curves away), so the swing solves for the pivot pitch that gives it. Pitch
* is clamped to [-89°, -5°] only in the direction of travel: a top-down view
* sits at -90°, below the limit, and must still be able to tilt up out of it.
* A pivot swing toward the horizon lowers the camera, so it stops at
* TILT_MIN_CLEARANCE_M and the rest tilts in place. Farther out it stops with
* the camera TILT_MIN_PIVOT_ELEVATION above the place's horizon instead, and

* down: a dim ember for weak fires through red, orange and gold to a pale
* white-hot core, lightness rising with power, so the brightest marks are the
* strongest fires. No cold hues: ~90% of detections are under 20 MW and a
* blue start painted most of the map blue. The thresholds are GEV's own, set
* on a real week's percentiles so every color appears: Portolan's
* 0/10/50/200/500/1000 MW leaves one hottest fire a week (HAL-675).
