storeToRefs()

function storeToRefs<S extends Record<string, unknown>>(
    store: S
): StoreToRefs<S>;

Splits a store's state and getters off into individually-subscribable refs — the same purpose as Pinia's storeToRefs(): destructuring a store directly (const { count } = counter) loses reactivity, since it copies the current value out at that instant rather than keeping a live binding. storeToRefs() gives you refs instead, which do stay live:

import { storeToRefs } from '@nekuta/core';

const counter = useStore(useCounterStore);
const { count, doubleCount } = storeToRefs(counter);

count.value; // stays in sync with counter.count going forward

$-prefixed store methods ($patch, $subscribe, etc.) and actions (any function-valued property) are excluded — only state and getters get turned into refs. Actions should be destructured directly off the store instead, since they don't need reactivity (const { increment } = counter is fine on its own).
