### Why? Because runes are not safe to toss around by design.

export function isRef(v) {
    return !!v && typeof v === "object" && Object.hasOwn(v, '__isRef');
}
export function ref(value) {
    let state = $state(value);
    return {
        __isRef: true,
        get current() { return state; },
        set current(value) { state = value; }
    };
}
