Claude 23a5a975ff feat: Vanna-Volga FX volatility smile tab
Builds the implied-vol smile from the three standard FX market quotes
(ATM delta-neutral straddle, 25-delta risk reversal, 25-delta butterfly)
using Castagna & Mercurio's second-order Vanna-Volga approximation, and
reprices each portfolio leg off the smile vs the flat vol.

- backend: core/vanna_volga.py (delta->strike, DNS ATM, VV smile) and
  POST /api/smile
- frontend: new "Vol Smile" dashboard tab with quote inputs, smile
  chart, pillar table and smile-vs-flat leg repricing

React + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

React Compiler

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.

Expanding the ESLint configuration

If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the TS template for information on how to integrate TypeScript and typescript-eslint in your project.
