Data and code for: Vibration-friction reduction in megalithic stone transport: quantitative physics constraints on acoustic and mechanical mechanisms across 12 sites

Computational code, block database, and room mode grid sweep data supporting the manuscript submitted to Journal of Archaeological Science. Includes: acoustic_transport_model.py (full computation), block_database.csv (12-site dimensional/mass data), room_mode_grid_sweep.csv (144-configuration Rayleigh mode analysis).
