Portfolio greeks (delta/gamma/vega/theta/vanna/volga) + SPAN-style scenario margin for an options book on Black-76. Given a list of legs {type, strike, expiryDays, iv, quantity(signed)} and a forward, returns aggregate greeks, first-order P&L per underlying move, and the worst-case loss over a price×vol grid. Self-checked: analytic greeks are verified against finite-difference derivatives of the repriced book. Call to size an options book's true net risk and margin — not the sum of per-leg notionals.
