Build a footer with status and region controls in Tailwind CSS: the standard link columns plus, in the bottom row, a live status badge (green dot plus 'All systems operational' linking to the status page) and a region selector showing the current data region (EU, US) with a link to switch. Keep both controls compact and functional — this is operational chrome, not marketing.
