 * A compact pill segmented control: a rounded pill split into option halves with
 * a hairline divider and a light-blue active tint. Shared so the same styling is
 * used by the namespace filters and the Git Configuration modal.
 *
 * Clicking the active option calls `onChange('')` (deselect). Callers that must
 * always keep a selection should ignore the empty value, e.g.
 * `onChange={v => v && setValue(v)}`.
