## What it does

The skill walks through the Hyvä workflow: theme setup and build tooling, Alpine.js components, Tailwind CSS styling, GraphQL data fetching from Magento's API, and performance tuning. Sections cover component architecture, custom Tailwind configuration, GraphQL caching, and Core Web Vitals — LCP, FID and CLS.

There is a separate part on module integration: third-party extensions, custom modules, bridging legacy code to Hyvä patterns, and headless setups. Code organisation and review practices get their own section too.

Everything here assumes Hyvä. On a Luma storefront the Alpine.js and Tailwind advice has nowhere to land, so check which theme your frontend actually runs before installing.
