Twin Chart Divergence Comparator (KP, two close birth times)

get_twin_differentiation

Takes two birth datetimes (typically 1-10 minutes apart) and computes how the twins' KP charts diverge: per-cusp longitude shift, sign / sign-lord / star-lord / sub-lord deltas, dasha balance diff (first MD lord, balance fraction, MD-end delta-days), per-event verdict / coverage / CSL deltas, and 'first material divergence age' (earliest age where MD or AD lords meaningfully differ). KP-precision proof-of-concept lens; the single strongest counter-argument to 'all twins get the same chart'.
