The 3D terrain showed almost no sky — the horizon sat far above the attitude
horizon line. Base camera pitch was 72°, but with MapLibre's 36.87° vertical FOV
the flat horizon only reaches the attitude line (28% of the SVT box) at ~82°.
Invert the perspective to derive the camera pitch from aircraft pitch so the
synthetic horizon lands exactly on the attitude horizon and tracks it 1:1
(accounting for the 1.5× canvas scale). Raise maxPitch to 85.
