## M2 acceptance in the real application. Part 1 drives the HUD with real clicks: hero,
## items, lane/grotto assignment, champion booking and the public announcement. Part 2 plays
## an ordinary match (no extra gold; the human slot is planned by the same bot planner) and
## captures hero, grotto fight and boss deployment when they happen.
## Run: godot --path . --resolution 1920x1080 res://tools/luneraria/verify_m2.tscn
