  Sitemap index (SEO_PLAN item 6, 2026-07-20) — converted from a flat <urlset>
  to a <sitemapindex> referencing two sub-sitemaps:
    - sitemap-static.xml: the curated marketing routes (this repo, frontend/public/).
    - sitemap-programs.xml: /grants/:slug program detail pages, generated
      dynamically by the Worker from D1 (worker/src/routes/sitemap.ts).
  robots.txt keeps pointing at this filename — Google follows the index to
  both children automatically.
