When to use it

Settings panels, volume/brightness controls, or any numeric input needing a high-contrast neon aesthetic on dark backgrounds.

When not to

Light-background UIs (background hardcoded dark plum). Production use requires wiring a real value-change callback and removing the auto-oscillation loop.

Working with an AI agent

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

Change the gradient from plum-teal to amber-gold by updating the two stop-color values in #fill to #A68D3F and #BFA98C, and slow the oscillation by changing t*0.018 to t*0.010. 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

  • gradient colors (stop-color in #fill linearGradient)
  • oscillation speed (t*0.018)
  • oscillation amplitude (0.42)
  • glow blur radius (feGaussianBlur stdDeviation)
  • knob radius (r=9)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard
  • visibilitychange pause
  • bubble clamp logic (Math.min/Math.max on bx)
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Auto-oscillates by default — remove the !manual sine loop for production use
  • Not keyboard accessible (no input[type=range] underneath)
  • Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default

  • Liquid ToggleSVG toggle with a goo filter — the knob slides with trailing liquid droplets; track color fades between off and on states.
  • Spring StepperMint-themed +/- stepper with a number reel that springs and overshoots between digits 0–9; auto-cycles as a demo. Dark green palette.
  • Segmented ControlSlate-to-sage gradient pill slides between Day/Week/Month/Year segments with elastic spring stretch. Auto-cycles; click pauses briefly.
  • Checkbox MorphThree amber rounded checkboxes auto-cycle and respond to clicks; the box fills and a checkmark strokes in via animated dashoffset.
  • Star RatingFive gold stars auto-sweep ratings up and down; the active star pops with a scale bounce. Pointer sets the hover rating instantly.
  • OTP BoxesFour teal monospace OTP cells auto-fill digits with a slide-up bounce and blinking caret; sequence clears and loops. Dark background with glow on active cell.
