Build a compact in-app footer bar with Tailwind CSS: a slim single-row strip with the product version, a status indicator (all systems normal with a green dot), and a locale selector on the right. Keep it visually quiet — small muted text on the app background — and make it the place where build numbers and environment labels (production, staging) live.
