  IMPORTANT: We intentionally limit pSEO sitemaps to prevent crawl budget waste.
  Previously 327,520 tool URLs were submitted causing 97% rejection rate.
  Only high-value pages are now included.

    REMOVED: sitemap-tools-0.xml through sitemap-tools-9.xml
    These contained 327,520 programmatic pages that Google was refusing to index
    (97% rejection rate = active crawl budget drain and domain trust damage).
    Strategy: Only re-add when pages have unique, substantial content.
