//! # volsurf
//!
//! Production-ready volatility surface library for derivatives pricing.
//!
//! Provides the full pipeline: raw option quotes → implied vol extraction →
//! parametric surface fitting → arbitrage-free enforcement → local vol / pricing
//! engine input.
//!
//! ## Architecture
//!
//! - **`implied`** — Implied volatility extraction (Black, Bachelier, displaced diffusion)
//! - **`smile`** — Single-tenor smile models (SVI, SABR, cubic spline)
//! - **`surface`** — Multi-tenor surface construction (SSVI, eSSVI, piecewise)
//! - **`local_vol`** — Dupire local volatility extraction
