ahuma1104/rrg-dashboard — reverse-engineered prompt

Build me a simple browser based RRG dashboard that works from this project as a single page. I want it to feel clean and modern, with the main information shown visually instead of just raw numbers. Give me a clear title area, a few summary stats, a chart or visual panel for the RRG view, and basic controls so someone can switch between sample data sets or time ranges without getting lost.

Please make it responsive so it looks decent on a laptop or tablet, and keep the experience smooth and easy to understand for a casual user. If there is no real data source yet, use realistic mock data so the page still feels complete. Add sensible loading, empty, and error states instead of leaving blank sections.

Keep it easy to run with minimal setup, ideally just opening the page locally. Also leave the code organized and readable so I can swap in real data later. If you need to, look up current examples of RRG dashboards online and follow common patterns.
