| // The technique is a combination of using fontfaceobserver and storing data-uri | |
| // encoded fonts in the localstorage for perfect font loading experience. | |

| // by simply swtiching from fallback to primary typeface when fonts are loaded. | |
| // Permanently caching fonts as a CSS file in localstorage completely eliminates FOUT on subsequent visits. | |
