Dreamodus da352d3695 Audit fixes: a11y, gesture correctness, math edge cases 
- Keyboard focus-visible ring on all controls (WCAG 2.4.7), suppressed
  for pointer grabs; focusRing prop to customize or disable
- aria-orientation on track modes; data-dragging/-disabled/-readonly/
  -focus-visible state attributes; disabled dims, readOnly drops the
  grab cursor
- Escape cancels a drag and restores the pre-gesture value
- Controlled mode no longer desyncs when the parent rejects onChange
- Second concurrent pointer can no longer hijack a drag session;
  drags cancel when disabled/readOnly flips mid-gesture
- Wheel: onChangeStart symmetry, settle flush on unsubscribe, dominant-
  axis direction (fixes macOS Shift+scroll reversal), ignored mid-drag
- Shift+wheel and fine multipliers now work on stepped/values knobs
- Fader/LEDFader track mapping inset-aligned with handle travel (no
  value jump when grabbing the cap); LEDFader zones sorted
- roundTo no longer returns NaN for exponential-notation values;
  logTaper falls back to linear for invalid ranges; decimalsFromStep
  shaves float noise; findClosest([]) returns the input
- Double-click reset brackets with onChangeStart/End
- MetalKnob honors showValue/unit/format; VintageKnob omits them from
  its type; TickLabels extracted as a public primitive
- SegmentDisplay: letters/hex charset, dash overflow instead of 888

Path What it is
packages/dreamknob The library. Zero runtime dependencies, ESM + CJS + .d.ts.
apps/docs Vite showcase: gallery, live playground with code generation, API docs.

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.

See packages/dreamknob/README.md and the docs app for the full API.
