  Sitemap for hyperspheretech.com
  Updated: 2026-05-15
  
  CHANGES FROM PREVIOUS VERSION:
  - Added <lastmod> to every URL (replace placeholder dates with actual last-edit dates before deploy)
  - Tuned priority values to match strategic importance
  - Changed blog changefreq from "yearly" to "monthly" (crawler signal only; doesn't claim content updates)
  - Added commented-out future pages from AI SEO Plan v1
  
  ACTION BEFORE DEPLOY:
  - Replace lastmod placeholders with real last-edit dates from your CMS/repo
  - Decide whether /contact and /request-demo are both needed
  - Decide whether /news-* posts move under /blog (recommended) or get their own index
  
  LONGER-TERM:
  - Migrate to app/sitemap.ts in Next.js so lastmod becomes automatic
