   components/color.css — Majestic V2 color control
   ------------------------------------------------------------
   Track C. A swatch plus an editable hex value, backed by a native
   <input type="color"> that stays the submitted fallback source.
   The saturation/value area, hue and (opt-in) alpha sliders live in
   a portalled panel anchored on desktop and presented as a bottom
   sheet on narrow phones. Six-digit hex is the default format.

   Namespaced (.majestic-color-field / .majestic-color-panel) away
   from the legacy .majestic-color-* picker.
