PrismColorPicker class

A compact HSV colour picker with hue/saturation/value drag surfaces and a hex text field.

Two orthogonal surfaces: a saturation/value square for the currently selected hue, and a hue bar below it. A hex field mirrors the current colour, so users can paste a brand colour exactly.

PrismColorPicker(
  color: theme.colorScheme.primary,
  onChanged: (c) => setState(() => accent = c),
)
