Three post-deploy checks I run after every Cloudflare Pages build

To prevent production issues, a developer implemented three post-deploy checks for sites aiappdex.com, findindiegame.com, and ossfind.com using Astro 5 SSG on Cloudflare Pages. These checks address specific failure modes, such as a sitemap _redirects rule blocking sitemap-index.xml and Bluesky image upload race conditions caused by deploy lag. The first essential check involves verifying that sitemap-index.xml is reachable and returns a 200 status code across all three domains immediately following every Cloudflare Pages build.
