Leaves: alpha-tested cards (texture drawn procedurally for leafShape), vertex colours with per-card variation,
per-instance hue / saturation shift and crown thinning (densityVariation), normals that are not flipped on back
faces (so a crown shades as one volume), back-lit translucency towards the sun, wind sway plus flutter. Weather:
wet leaves darken, snow settles, burn scorches them brown then black and drops them, damage drops leaf mass.
