//! Example: Create a Codex document from scratch.
//!
//! This example demonstrates how to use the DocumentBuilder API
//! to create a new document with content, metadata, and save it.

use cdx_core::{Document, Result};

fn main() -> Result<()> {
    // Create a new document using the builder API
    let document = Document::builder()
