GENERAL! September 12, 2026 GENERAL! Day 1 Iteration 13

Functional Battlefield Terrain

Added two tree groves, two rock outcrops, and a four-tile pond to the meeting-engagement battlefield.
Terrain is functional rather than decorative: formations cannot occupy or path through those tiles.
Player reachable-tile previews, persistent pathfinding, melee approaches, and AI destination selection all respect terrain blockers.
Kept broad central and flanking lanes open so the introductory battle remains maneuverable.
