        How edge is computed: Pinnacle (sharp book) two-sided ML price is

        devigged to a no-vig fair probability per side. For every other

        book''s offered price on the same side, edge = fair_prob -

        book_implied_prob. Anything above 0 is a "+EV" play vs Pinnacle as

        anchor.
