  Sitemap index for the Causality Engine entity (www host).

  Points search engines and AI crawlers at the marketing domain
  sitemap (causalityengine.ai/sitemap.xml, ~2,000 URLs).

  Same-host rule: a sitemap index may only reference sitemaps on
  the same host, so the app-domain sitemap
  (app.causalityengine.ai/sitemap.xml, the Attribution Report
  Library + report detail pages) is intentionally NOT listed here.
  It is cross-referenced for crawlers in robots.txt
  (Sitemap: https://app.causalityengine.ai/sitemap.xml), which is
  the protocol-correct place for cross-host discovery.

  Why this matters for AEO/GEO:
    - One root URL to submit to Google Search Console + Bing
      Webmaster Tools that covers this property.
    - Reinforces that the two domains are one organization in
      Google's eyes (paired with Organization.sameAs in
      app/layout.tsx, which includes app.causalityengine.ai).
    - Lets AI crawlers (GPTBot, ClaudeBot, PerplexityBot,
      Google-Extended) discover the report-library content via
      robots.txt as part of this entity rather than as a separate
      property.

  Reference URL pattern (submit this to GSC + BWT):
    https://www.causalityengine.ai/sitemap-index.xml
