Real outputs, not mocks

Market-scaled greeks, ready for the desk.

Vega per 1% vol, theta per calendar day, rho per 1% rate. Cash delta and cash gamma scaled by lot size and contract multiplier — same numbers a desk uses to hedge.

Built on the same Black-Scholes-Merton engine that drives the 3D surface above. Closed-form when possible, Fourier integration or binomial trees when it's not.
