satellite.trail_time_scale

Multiplier on the authored lifetime of the satellite's trail renderers — a trail spans this many times the authored seconds of flight path, so it directly scales the visible streak length. Applied as the trails switch on (they sit out the projected far-distance stretch and only run once the satellite is drawn at its real position), so changes take effect at the next handover, not mid-trail. Replicated because trails render client-side.
