<p>Interwebbi’s Asset Inliner is a performance plugin that focuses on practical frontend asset optimization:</p>
<ul>
<li>Inlines local frontend CSS from stylesheet links.</li>
<li>Rewrites relative CSS asset URLs so fonts/images still work after inlining.</li>
<li>Optional CSS minification.</li>
<li>Optional Google Fonts localization (detects Google Fonts stylesheets, downloads font files to local uploads, rewrites font URLs to local files, and inlines the rewritten font CSS).</li>
<li>Optional font-display policy override for localized Google Fonts (<code>keep</code>, <code>swap</code>, <code>optional</code>, <code>fallback</code>, <code>block</code>).</li>
<li>Optional preload tags for localized WOFF2 fonts.</li>
<li>Automatic cache busting on post/page saves, deletions, theme switches, updates, and plugin settings changes.</li>
</ul>
<p>Google Fonts localization is optional and disabled by default.</p>
