/* ════════════════════════════════════════════════════════════════════════════
   METRICS — the signature "live-metrics" language: ring charts, comparison
   bars, dashboard frame. One implementation, used on every page that shows
   outcomes. Colours come exclusively from --viz-* tokens.
   Animation: app.js adds .is-visible on first reveal; without JS everything
   renders at its final value.
