Build a documentation header bar with Tailwind CSS: the product logo and name, a breadcrumb of the current doc section, a version switcher dropdown listing the latest release plus two archived ones, and a small 'viewing an older version' notice when an archived version is selected. Add a search field and a GitHub link on the right, and keep the bar sticky so navigation stays reachable in long docs.
