Picket fence along a path

Build a picket fence that follows a path of ground points: capped posts at corners and at even bay spacing, two rails per bay following the ground slope, and evenly spaced pickets with pointed, flat, round or dog-ear tops. Use it for gardens, farms, suburbs and game levels.

Limits to consider

Pickets stay vertical and their bottoms step along a straight ground line between path points; uneven terrain between points is not followed. No gates, diagonal braces or rail joinery. Every part is a separate closed solid that touches its neighbours. Verified in Blender 5.2.1; written for the 4.2 API.
