  This is a static, manually-maintained sitemap for the current SPA architecture.
  Update lastmod dates and add/remove entries on content changes.
  After migration to SSR/SSG or a proper router + prerender, replace with
  an auto-generated sitemap (e.g. via vite-plugin-sitemap or next-sitemap equivalent).

  Primary domain placeholder: https://www.peptidesresearch.com
  Replace with production domain before GSC submission.
