So @blog@blog.fedidb.com is a homemade blog, built with a prototype of my laravel-activitypub package!
But, https://fedidb.com isn't Laravel, its a Nuxt v4 SSR javascript app.
The blog is hosted on the Laravel backend of FediDB, fedidb.org, but it leverages Laravel's domain routing feature to use blog.fedidb.com which the Nuxt app proxies the webfinger of.
Why? Because I can. 🤘
