## Key Recommendations

- **Prefer Setup Stores** for complex logic, composables, and watchers
- **Use `storeToRefs()`** when destructuring state/getters to preserve reactivity
- **Actions can be destructured directly** - they're bound to the store
- **Call stores inside functions** not at module scope, especially for SSR
- **Add HMR support** to each store for better development experience
- **Use `@pinia/testing`** for component tests with mocked stores
