- TCL Chinese Theatre (6925) and Madame Tussaud's (6933) exported from the verified OSM blockout with ue_metric_v1 (export_north_buildings.py), with a Y-mirror so they land north of the road, across from the hero facade. - ue_import_north_buildings.py imports + stages them in the DemoMap as North_TCL_Chinese / North_Madame_Tussauds (TCL Y 1802..9431, Tussaud's 1888..7586; hero at Y -1450, road centreline ~0). - render_screenshots.sh now also runs the DemoMap capture pass; added a demo-north-buildings camera, so the new buildings get a review shot. - README/roadmap updated; flat facade materials pending the 0.1.4 patch.
