Add south_bound_lat to modes.yaml and a load_south_bound() helper in prepare.py. When set, the area geometry is intersected with the north half-plane above the cutoff, so all downstream clipping (lines, stops, stations) cascades automatically. Removed: 94 bus stops (including Skyttehøj), 1 station (Vestamager), and line segments south of the boundary (Metro M1 tail, buses 32-36).
