Font Awesome icons with fonts bundled in base64
Only Font Awesome 6 free icons ( with solid and brand icons ) are bundled as ./all.css.

Bundled version gives convenience to handle the required file with a single file format, so that even if you bundle HTML or use any other bundlers like Webpack the font file wouldn't run away but instead remain bundled as base64 encoding which the browser would be able to understand and render those.
You can checkout ./example.html to see if the fonts are working correctly.
You can check ./scripts/sync.ts of how the bundling is processed.
We use PostCSS to bundle the CSS file.
