Core Purpose: This library is a comprehensive Vue 3 framework for reactive application architecture. It provides high-level abstractions for API orchestration (fetching, mutation, SSR, schema validation), state management (singletons, reactive storage, session/cookie handling), component design (base classes for rendering and lifecycle management), and localization/internationalization (geo-data, formatting, date management).

Usage Scenarios: Study this API when building complex, data-intensive Vue 3 applications requiring:
1. Centralized, reactive API management (GET/POST/PUT/DELETE) with built-in SSR support, caching, and automatic response contract validation.
2. Unified component architecture using base design classes for consistent styling, rendering, and lifecycle event management.
3. Complex list handling, client-side searching, and advanced data formatting (Intl, currency, dates).
4. Cross-tab communication or persistent reactive state storage (localStorage, sessionStorage, cookies).
5. Global service configuration (meta tags, translation, icons, API settings) via Vue plugins.

Integration Context: The library acts as a core infrastructure layer. It is built on top of Vue 3's Composition API and `vue-router`. It relies heavily on `@dxtmisha/functional-basic` for underlying logic. It should be treated as the primary service and utility layer that replaces manual store management (like Pinia) and repetitive API/lifecycle boilerplate by providing standardized patterns (e.g., `executeUse` for singletons) for shared state and service orchestration.
