## Summary

Deliver `@suaveplan/react-bank` on the genesis branch from scratch at enterprise quality. The package provides React components and hooks for a game-banking UI. A typed `BankClient` wraps `@suaveplan/api-plugin-bank` HTTP endpoints; a `BankProvider` context holds account state, loading, and error; `useBank()` exposes the context; six pre-built components cover account list, balance display, interest rates, open account form, transaction history, and transfer form. English locale pack included for `@suaveplan/i18n` under the `bank` namespace. Genesis adds Storybook stories, Vitest DOM tests, and 100% coverage.
