The library in 10 seconds

import { MetalKnob, LEDKnob, Fader, logTaper } from 'dreamknob'

<MetalKnob size={90} min={0} max={100} step={0.5} defaultValue={64} label="Gain" />
<LEDKnob min={20} max={20000} taper={logTaper} defaultValue={632} label="Freq" />
<Fader min={-60} max={12} step={0.5} unit=" dB" defaultValue={-6} label="Out" />

• Feel: grab-and-rotate rotary tracking (rc-knob style), or relative vertical / horizontal drag (DAW plugin style), or absolute track dragging for faders. Scroll-wheel nudge, full keyboard support, Shift for fine control, double-click reset, touch via pointer capture, proper role="slider" accessibility.
• Numbers: any range (negative, fractional, huge), decimal step with float-drift-safe rounding, discrete values lists, evenly spaced detents (steps), linear / log / power / custom tapers.
• Styles: FlatKnob, MetalKnob, RubberKnob, VintageKnob, LEDKnob, NeonKnob, SteppedKnob, Fader, LEDFader, SegmentDisplay — every color themeable per instance.
• Composable: <Knob> + primitives (Arc, Pointer, Ticks, Face, KnobValue, KnobLabel) for custom designs, or go fully headless with useKnob.
