Accessibility
- Give ComboboxInput an accessible name, such as with aria-label or an associated visible label.
- Use meaningful text for options and group labels so choices remain understandable without relying on icons or styling.
- Disabled state is forwarded from ComboboxInput to its input and trigger/clear controls.
- The check, chevron, and remove icons are visual affordances; do not use them as the sole accessible name for a control.
