Simulation#
A compiled scene is solved either by Sionna RT or by an analytical CPU preview. Requests and
dataset cases select between them with the engine field.

Free-space path loss with directional and building obstruction penalties; always available |
Both return the same product: non-negative linear float32 arrays for path gain, received
power and SINR with shape (n_tx, rows, columns), an integer association grid, and ENU cell
centres ordered south to north. Conversion to dB and dBm, PNG rendering and export belong to
the common output layer.
Terrain-following measurement surfaces, propagation switches, geometry masks, SINR.

What cell_size and samples_per_tx do, and what they do not.
