+Each live hop follows its confirmed geographic segment. In 3D, trails and residue follow sampled terrain while ground rings respond to the camera; historical routes drape over the same terrain. Topo turns on with 3D, with 1.35x elevation exaggeration. Date-line strokes split at the world-map seam without creating extra hops or notes. Its cue uses a sharp packet core, short glow, restrained sparks, relay handoff, destination shimmer, node wake, and bounded 45-second residue. Hiding Routes does not hide recent live traffic.
 
 Adaptive quality reduces secondary detail and backing resolution during bursts but does not discard visible route hops. Reduced-motion mode uses static cues. The renderer prohibits full-map flashes, additive white saturation, camera-relative route geometry, and effects that survive route expiry.
