  sitemap.xml — tells Google which pages exist on the site.
  Uses REAL URL paths (not hash fragments) thanks to History API routing.
  When Google crawls yoursite.com/flashcards, the server serves index.html
  and the JS router renders the flashcards page.

  The <lastmod> dates should be updated when content changes.
  <changefreq> is a hint, not a command — Google ignores it mostly.
  <priority> is relative (0.0 to 1.0); 1.0 = most important.
