When to use it

Settings panels, form demos, or any UI showcase needing a tactile checkbox feel with ambient motion.

When not to

Production forms requiring immediate user control — remove the auto-cycle clock loop before shipping.

Working with an AI agent

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

Change accent from amber to teal (#2dd4bf), increase checkbox count from 3 to 5, and slow the checkmark stroke to 0.10 lerp factor. 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 (#ffb02e)
  • checkbox count (loop 0..3)
  • auto-cycle interval (clock%150)
  • checkmark lerp speed (0.18)
  • corner radius (rx=20)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard with static checked fallback
  • visibilitychange pause
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Auto-cycles by default — remove the frame loop for production use
  • LEN=80 is an approximation; exact path length may cause slight overshoot on the stroke draw
