How accurate are the Tailwind classes Claude Code generates for Hyvä?

100% accurate to your tailwind.config.js — not generic Tailwind defaults. We seed CLAUDE.md with: “Always read tailwind.config.js before writing utility classes. If a colour / spacing / font scale isn’t in the config, propose a config edit instead of using an arbitrary value.” Claude Code also runs the Tailwind JIT compiler against generated phtml in CI — any class that doesn’t exist in your config fails the build before merge. Net result: 0 hallucinated utility classes across 80+ Hyvä projects shipped.
