What is Hyvä and why does my store need it?

Hyvä is the modern frontend framework for Magento 2, built on Tailwind CSS + Alpine.js. It replaces Magento’s default Luma theme (which uses jQuery + KnockoutJS) and ships with 5–10× faster page loads, Lighthouse scores in the 90–100 range, and core-web-vitals green by default. Stores that switch typically see conversion lifts of 8–25% from speed alone.
