Build me a polished React admin dashboard for AI operations and review workflows.

I want a static frontend only app with a dark, modern command center feel, something I can use as a starter for an internal tool or analytics product. It should have a responsive three pane layout, with a left sidebar, a main dashboard area, and a right side AI companion panel. Include useful dashboard pieces like KPI cards, small sparkline style charts, larger analytics charts, a task review queue, and an activity feed. On smaller screens, the side panels should collapse into drawers so it still feels good on mobile.

Make the UI look clean and dense, with strong spacing, good typography, and a clear operational style. Use realistic placeholder data and make the AI panel feel like it can help with diagnostics and review tasks. I do not need any backend, login, or API setup, just the full frontend experience ready to run and customize. If you need to check current docs for the best approach, go ahead and look them up.
