note: v0.1 placeholder site plan: SnS barge slab footprint (61x21 ft, dims imported from src/floatsauna/canon.py) centred in a generic 100x50 ft water window with schematic mooring ticks, north arrow, scale bar, and prominent SITE LOCATION TBD banner. No UTM, no real-world coordinates, no specific water body — site has not been confirmed and v0.2 will drop in the real berth once finalized. Canon does not yet define hull/pontoon dimensions separately from slab; v0.1 draws hull = slab outline.
