Module color_picker 

Event-driven: each press latches a DragTarget so a drag continues to track the cursor even after it leaves the widget rect (see wants_pointer_capture). All visuals pull colours from theme tokens — no literal palette values live in this file.

The selected colour can stay widget-local, bind to typed process-local state with ColorPicker::from_state, or be observed with on_change for an app-owned durable mutation.

Two optional parts extend the inline picker:

• Swatches (ColorPicker::with_swatches): a palette of quick picks below the sliders, each a radio button for assistive technology.
• Confirm mode (ColorPicker::confirming): a titled picker whose edits stay pending until Done; Cancel (or Escape) restores the colour it opened with. The host reads the result from ColorPicker::take_outcome or ColorPicker::on_outcome.

The saturation/value field and hue strip paint the real HSV gradients the pointer maps into; every chrome colour (edges, rings, labels, buttons) comes from theme tokens.
