  1. Keep Pages source explicit (gh-pages branch root) or move to a dedicated GitHub Actions Pages deploy workflow when you need tighter build control.
  2. Use a custom 404 page and keep navigation links shallow so users can recover quickly from broken URLs.
  3. If using a custom domain, verify the domain ownership and keep HTTPS enabled to reduce takeover risk.
