/**
 * Comprehensive Showcase and Template Content component.
 *
 * @description
 * This component serves as a living kitchen-sink demonstration of the Xertica UI
 * Design System. It showcases almost every UI primitive (Cards, Tabs, Forms,
 * Tables, Dialogs, etc.) and layout variation (Header flexibility, Sidebar
 * toggling). It's primarily used for development, testing, and as a starting
 * point for new pages.
 *
 * @ai-rules
 * 1. Reference: Use this component as the primary source of truth for "how to compose" complex layouts in this library.
 * 2. Layout: Adjusts its own padding based on the `useLayout` context's sidebar state.
 * 3. Interaction: All showcase interactive elements (buttons, forms) use simple `toast` feedback or local state toggles.
