I also prototyped how to make this work reliably for async scripts via a single capturing load event listener on the document: github.com/westonruter/...

Nice. We were looking at doing something like this for core but we didn't end up doing it (yet): core.trac.wordpress.org/ticket/58632

No, I haven't.

I'm working on a Dev Note for all the performance improvements, but in the mean time here is a gist of what's included: gist.github.com/westonruter/...

Thanks for inviting me!

This closely aligns with what I was saying in my recent talk at WordCamp US: just because something is good doesn’t mean it can’t be better!

I'm super excited to see all of this happen on Glisan ASAP! I can't wait for how these changes will improve pedestrian safety, facilitate cycling, and calm traffic to reduce the frequent speeding and racing that happens in these 10 blocks between 82nd and 92nd. And thank you, @pbotinfo.bsky.social!

For intra-site navigations, I think speculation rules with moderate eagerness and prerendering is the much easier solution.

I'll check it out! Yeah, good point that a PWA can all but eliminate TTFB when using cache-first or stale-while-revalidate, but only for repeat visitors. But there is still the service worker startup cost since you can't use navigation preload.

A script printed any other way (including in event handler attributes) will be blocked from execution since it could have been added due to an XSS exploit. These will appear as errors in the console.

To be compatible, themes and plugins must not print <script> tags directly. Instead, they must use the proper APIs: wp_enqueue_script(), wp_add_inline_script(), wp_localize_script(), wp_print_script_tag(), wp_print_inline_script_tag(), wp_enqueue_script_module() and the like.

I just wish that the Gemini Code Assist plugin for JetBrains (PhpStorm) also automatically read from this .gemini/codestyle.md instead of requiring manual configuration of the prompt library in settings (i.e. copy the file contents and paste as the rules).
