Feedback & States

Empty State

A Bauhaus open vessel sits empty while 26 mint motes drift in a slow orbital cloud above it; poking scatters them and they spring back to settle.

When to use it

Empty list pages, zero-data dashboards, or onboarding states that need a polished illustrated placeholder with subtle ambient life.

When not to

Contexts where motion competes with a call-to-action or form fields; background is hardcoded dark navy so it clashes with light UIs.

Working with an AI agent

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

Change the mote color from mint to amber by setting ACC to '#f59e0b', increase mote count N to 36, and slow the orbital wobble by changing t*0.0009 to t*0.0005. 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

  • mote count (N=26)
  • accent color (ACC='#34d399')
  • orbital drift speed (t*0.0009)
  • vessel scale (rw=64*u, rh=20*u)
  • scatter power in userPoke (3.2)
  • auto-demo interval (3200–4600ms)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion static fallback + early return
  • visibilitychange pause/resume guard
  • DPR-aware canvas sizing
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default
  • Auto-demo scatter fires on an interval even without user interaction; disable autodemo() call for purely passive use

  • Hold to ConfirmPress-and-hold fills a tick-marked ring; full hold rotates center square 45° into a green check; early release flashes red cross (cancelled).
  • Like BurstHeart dips then spring-pops into a magenta-mint gradient, firing a 96-particle synthwave burst of dots and ring shards. Auto-cycles when idle.
