MVA Global Fret 3f773380c4 Drop parachuted parcels behind the plane as it crosses ...

Adds a sprite-based parcel system. The plane spawns a new
parcel-on-parachute (assets/parcel.png, 236 KB transparent) every
~1.4 s while it's visible (progress 0.04-0.92). Each parcel:

- Spawns at the plane's current position with a tiny random offset.
- Falls at 1.4 world units/s, with a small horizontal drift and a
  parachute sway sinusoid for character.
- Scales 0.35 → 2.6 over its lifetime, simulating the perspective
  of falling toward the camera.
- Fades in over 6% of life, fades out over the last 15%.
- Cleaned up (removed from scene + material disposed) when its
  lifetime expires or it drops below y = -10.

Implemented as THREE.Sprite so it always faces the camera, no need
to track per-parcel orientation.
