ESLint running on CSS?

  0:0  error  Parsing error: ESLint was configured to run on `<tsconfigRootDir>/src/styles/globals.css` using `parserOptions.project`: /path/to/project/tsconfig.json
The extension for the file (`.css`) is non-standard. You should add `parserOptions.extraFileExtensions` to your config

// eslint-disable-next-line @typescript-eslint/no-var-requires
const path = require('path');
