User report: 'el selector del cuadro de colores, no tiene semántica, es
un drag, etc como el slider, no?'
You're right — the 2D area is a drag interaction with the same shape
as a slider. It was wiring pointer events to soma state but staying
silent to sema; nothing for sounds/haptics/transient styles to hook
onto. Now it speaks the same vocabulary as the slider.
Morfo additions (color-picker)
------------------------------
- `handle-pick` (family: handle, verb: pick, sequence: coincident,
target: area) — fires once at pointer-down.
- `handle-drag` (family: handle, verb: drag, sequence: coincident,
target: area) — fires on each move (pointer or keyboard step).
- `commit-set` already existed — now also emitted on pointer-up and
on each keyboard step (slider parity).
Soma changes (color-picker-provider)
------------------------------------
- ColorPickerAreaProvider:
- `onpointerdown` → trigger `handle-pick` then continue to drag.
- `handlePointerMove` → trigger `handle-drag` after writing the value.
- `onpointerup` → trigger `commit-set` then `commitChange()` for
the onValueChangeEnd callback.
- ColorPickerAreaThumbProvider.onkeydown:
- Each arrow / Home / End / PageUp / PageDown step now triggers
`handle-drag` + `commit-set` + commitChange(). Matches the slider's
keyboard semantics (one step = one drag + one commit).
Demo snippet refresh
--------------------
The `somaSnippet` / `eidosSnippet` in `/uix/components/color-picker`
were stuck on the pre-refactor API (`<ColorPicker.Area>` with explicit
Background+Thumb children, no `Control`, no `ValueSwatch`, no
PickerShell footer). Updated both to mirror the current demo body:
- Eidos: `Label / Control[Trigger + ValueText + HiddenInput] / Portal /
Content[Area / ChannelSlider hue / alpha / ValueSwatch +
ChannelInput + EyeDropper / SwatchGroup / Footer[Clear/Cancel/
Close]]`.
- Soma: same shape but uses `PickerShell.Footer / Clear / Cancel /
Close` explicitly (and the explicit Track/Thumb composition on
channel sliders for the curious).
- Both snippets honor the live `mode / inline / closeOnSelect /
enableAlpha / showFooter / showClear / showCancel / showClose`
flags from the chip controls.
