I expected something clearer in the blog post about deploying Astro on Cloudflare Pages, as I imagine many Astro users (like me) are on Netlify.
I think every deployment pipeline having it's own preferred UI framework (and CMS, and cloud-DB solution) makes a lot of sense.
Why did you expect info about deploying Astro to Cloudflare Pages? It's been supported for a long time already.
