@bolt/components-critical-css

Note: This package will be removed in Bolt v3.0 when we drop IE11 support, modern browsers support async CSS loading natively. See migrating to Bolt v3.x docs for more info.

Adds automatic <link rel="preload"> async CSS Loading support for browsers that don't natively support it (via the Filamentgroup's invaluable [loadCSS])(https://www.npmjs.com/package/fg-loadcss) library).
