Adds the five remaining verified south-side buildings to the demo block (6922, 6902, 6838 El Capitan Theatre, 6822 Budget, 6806-6820, 6800 Lee Drug) exported in place from the OSM blockout and staged by the demo builder. Adding neighbours exposed a pre-existing placement bug that could not be seen while the hero stood alone: - UE south is +Y (south sidewalk Y +718..+1447), but the hero facade sat at Y -1450 on the NORTH side and at X -12024..-9420, which is 26 m east of the 6840 footprint (the frontage gap is X -14591..-12082). - The two north-side buildings were on the SOUTH side, because their exporter mirrored Y. Fixes: hero moved to X -13336 / Y +1307, inside its frontage gap; frontage and north buildings export without a Y mirror (the FBX preset already lands Blender -Y south on UE +Y south); player start and demo cameras moved to the north sidewalk looking south; sun raised to pitch -62 so both frontages read instead of the north side going to silhouette. Screenshots re-rendered; the four demo views are marked needs-review because the whole block changed.

# position preserves the offset from the hero facade. The site export preset
