- nearest_trail_distance2 now measures point-to-segment distance to each
trail edge instead of only to stored points, with a single-point fallback.
- Tree height scaling keeps canopy proportions; maturity adds subtle
variation instead of shrinking young trees to bare poles.
- Raise forest spawn probability and tighten spacing for denser, more
coherent stands; redwoods cluster a bit closer.
- Cabins near trails favor a wooded setback off the centerline; the spur
still connects.
