/**
 * The next/font postcss plugin recieves the @font-face declarations returned from the next/font loaders.
 *
 * It hashes the font-family name to make it unguessable, it shouldn't be globally accessible.
 * If it were global, we wouldn't be able to tell which pages are using which fonts when generating preload tags.
 *
 * If the font loader returned fallback metrics, generate a fallback @font-face.
 *
 * If the font loader returned a variable name, add a CSS class that declares a variable containing the font and fallback fonts.
 *
 * Lastly, it adds the font-family to the exports object.
 * This enables you to access the actual font-family name, not just through the CSS class.
 * e.g:
 * const inter = Inter({ subsets: ['latin'] })
 * inter.style.fontFamily // => '__Inter_123456'
