"""Tests for Tools/ue_placement.py — the single source of truth for placement.
|
|
|
|
A regression test for a real bug: `ue_hero_facade_import.py` carried its own hero
|
|
position (the pre-0.1.0 one) while `ue_build_demo_map.py` staged the verified one.
|
|
Running the importer moved the hero 13 m east and onto the north side of the
|
|
boulevard, and nothing complained because a displaced building still renders.
