/* Kodza — Color Picker
   A real colour input, dressed up: the field shows a swatch and the hex code, and a
   panel opens with a saturation / brightness square, a hue slider, a hex field, presets, the
   browser's eyedropper (where it exists) and a copy button. Pick a preset and the colour
   travels there: both handles glide and the square turns with them. The real input stays in step.
   The panel itself stays monochrome. Same box as Select.
   Everything is tuned with the --kz-color-* variables. */

// brightness (drag, or arrows: Shift for bigger steps), the slider sets the hue, the hex field
