v2 changes. Three boards (anterior, posterior V7–V9, right-sided V4R/V5R/V6R), two body types (standard, female with V4–V6 inferior placement), per-electrode tolerance (precordials tighter than limb leads), true HTML5-style drag-and-drop with mouse and touch support, and a Reversal mode that demonstrates the six standard limb-lead reversals using clinically-validated derivation tables. Clinical-content note: female-body adjustments are framework-only and need clinical reviewer sign-off before deployment.
