Quick Metrics Dashboard UI

I need a small web dashboard delivered within the next 2–3 days. I already have some starter layouts drafted with Claude; your job is to turn that rough scaffold into a tidy, working interface that pulls live system-performance data from our database.

The dashboard will surface three key metrics for our web-scraping pipeline: overall success rate (%), error rate (%), and the total volume of data extracted (MB). A simple, modern look is enough—think clean charts or gauges that refresh automatically every minute.

You will get read-only database access, schema notes, and a couple of sample SQL queries. Feel free to use React, Vue, or another lightweight front-end, plus a slim Node/Express layer if you prefer to keep credentials server-side. The finished code should live in a Git repo, install with a single npm command, and run locally without extra setup.

Acceptance criteria
• All three metrics display correctly from live data
• UI updates in place (no full reloads) and loads in under two seconds
• Code is clean, commented, lint-passable, and accompanied by a short README
• Everything is delivered inside the 2–3-day window

That’s the whole scope—quick, specific, and ready for someone who can move fast.
