  Cross-domain sitemap index for the Causality Engine entity.

  Points search engines and AI crawlers at both the marketing
  domain sitemap (causalityengine.ai/sitemap.xml, ~2,000 URLs)
  and the app domain sitemap (app.causalityengine.ai/sitemap.xml,
  the Attribution Report Library + report detail pages).

  Why this matters for AEO/GEO:
    - One root URL to submit to Google Search Console + Bing
      Webmaster Tools that covers both properties.
    - 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 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
