//! Card widget for grouping related content with visual boundaries
//!
//! Cards provide a structured container with optional header, body, and footer sections.
//!
//! # Example
//!
//! ```rust,ignore
//! use revue::widget::{Card, card};
//!
//! // Basic card with title
//! Card::new()
//!     .title("User Profile")
//!     .body(user_info_widget);
//!
//! // Card with header, body, and footer
//! card()
//!     .title("Settings")
//!     .subtitle("Configure your preferences")
//!     .body(settings_form)
//!     .footer(action_buttons);
//!
//! // Collapsible card
//! Card::new()
//!     .title("Details")
//!     .collapsible(true)
//!     .body(details_content);
//! ```
