1//! # Ferrox Front UI (`ferrox-front-ui`)
2//!
3//! `ferrox-front-ui` provides an enterprise-grade Glassmorphism Design System for WebAssembly:
4//! 12-column responsive layout grid (`Container`, `Row`, `Col`), Virtualized DataGrid (1,000,000+ rows),
5//! Design Tokens, and UI components (Buttons, Badges, Cards, Form Controls, Avatars, Progress Bars, Toasts, Spinners).
