A sensor item couples a 3-D position with an optional 3x3 coil-orientation matrix (embedded in a 4x4 for GPU upload). The renderer picks a primitive per sensor type: oriented plate for MEG magnetometers, barbell for gradiometers, sphere for EEG. Without an explicit orientation the sensor falls back to a world-aligned sphere — useful for raw position dumps.
