Gauge

A semicircular (half-circle) gauge / dial that shows a single measurement within a known range, drawn with an SVG arc that fills from the left with a smooth animated transition. Use it whenever you want an at-a-glance meter rather than task progress: CPU/memory/server load, disk or storage usage, API rate-limit or quota consumption, a health/uptime or performance score, a speedometer, temperature/humidity, battery or signal level, a credit/risk or Lighthouse-style score, or a KPI/target attainment dial. Set `segments` to change the arc color at thresholds — e.g. green under 60, amber under 85,
