 * Builds static sitemap entries for publicly-indexable pages.

 * Also excluded: `/manage` (admin dashboard, noindex), `/search`
 * (parameterized results, no canonical representation), `/profile`
 * (user-specific), `/compare` (parameterized tool), and any `/api/*`
 * routes (robots.txt disallow).
