import { SPRING_SNAPPY } from '@/lib/motion';
export interface SegmentOption<T extends string> {
value: T;
label: ReactNode;
icon?: ReactNode;
}
/** 胶囊轨道 + 弹簧滑块（2px 内边距，999px 圆角） */
export function Segmented<T extends string>({
value,
onChange,
options,
ariaLabel,
}: {
value: T;
onChange: (v: T) => void;
options: SegmentOption<T>[];
ariaLabel: string;
}) {
const id = useId();
return (
<div role="radiogroup" aria-label={ariaLabel} className="inline-flex rounded-full bg-ghost-selected p-[2px]">
{options.map((o) => {
const active = o.value === value;
return (
