Interesting! Zeta23 already has `Cf r f` — this is exactly the "g" function: f divided by the product over zeros in the disc of radius r, with the cofactor at zeros themselves. And `CfAnalytic` gives analyticity on closedBall(0, R). Let me look at more of the Cf API — there may be lemmas about nonvanishing and norm bounds. Let me grep for Cf lemmas.
Zeta23 already has `Cf r f` — the Blaschke-quotient g built in. Let me see its full API.
