Twin-breast FOV Phase A/B review with all STEP loop projections

Scope: STEP-derived receive surrogate, unloaded ideal-decoupled layout surrogate, Psi=I. Not measured g-factor, not true SNR, not EM-validated, not clinically validated.

Display change: The circular ROI has been removed. Maps are scaled and summarized within a twin-breast tissue ROI; the medial gap is excluded. The displayed FOV covers all extracted STEP loop/edge traces.
