  Sitemap for Hygeia Life Systems.

  Listed: 18 public marketing pages with priorities tuned for SEO discovery.
  Excluded: authenticated routes (/patient, /clinician, /admin, /caregiver),
  short-lived demo-token routes (/d/<token>) and the API surface.

  Update lastmod when page copy materially changes. Frequency hints reflect
  reality: home and condition pages are stable but may be tweaked weekly;
  about/security/contact change rarely.
