/**
|
||||
* 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'
