Overview

I'd missed that @vitest/eslint-config has a type-checking option! https://github.com/vitest-dev/eslint-plugin-vitest/?tab=readme-ov-file#enabling-with-type-testing

// eslint.config.js
settings: {
  vitest: {
    typecheck: true
  }
},

I'll want to enable that so that it can properly pick up functions used as test titles. 🚀
