When to use it

Dashboards, live metric displays, or hero stats counters needing a tactile mechanical feel.

When not to

Contexts requiring exact real-time data binding — target is random; wire tgt externally before shipping.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change the label to 'USERS ONLINE', set the accent color COL to '#ff9f43', and slow the easing by changing 0.045 to 0.02. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

  • accent color (COL='#7af0c0')
  • digit count (DIG=6)
  • easing speed (0.045)
  • label text ('REQUESTS / SEC')
  • target range (Math.random()*1000000)
  • hold idle delay (hold>80)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard (reduce=...matches)
  • visibilitychange pause
  • DPR-aware canvas sizing
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Target value is random — must replace tgt assignment with external data source for real metrics
  • Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default
