Interwebbi's Asset Inliner

Interwebbi’s Asset Inliner is a performance plugin that focuses on practical frontend asset optimization:

• Inlines local frontend CSS from stylesheet links.
• Rewrites relative CSS asset URLs so fonts/images still work after inlining.
• Optional CSS minification.
• 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).
• Optional font-display policy override for localized Google Fonts (keep, swap, optional, fallback, block).
• Optional preload tags for localized WOFF2 fonts.
• Automatic cache busting on post/page saves, deletions, theme switches, updates, and plugin settings changes.

Google Fonts localization is optional and disabled by default.
