//! Component system for building reports
//!
//! Components are the building blocks of reports. Each component has:
//! - A unique ID (e.g., "score-card", "finding", "audit-table")
//! - Data requirements (what data it expects)
//! - A Typst template that renders it
//!
//! ## Standard Components
//!
//! - `ScoreCard` - Display a metric with score visualization
//! - `Finding` - An audit finding with severity
//! - `AuditTable` - Tabular data for audit results
//! - `Section` - Document section with heading
//! - `Image` - Image with optional caption
//! - `Callout` - Highlighted information box
//! - `SummaryBox` - Executive summary widget
