coding-agent-search 0.5.1

//! HTML export module for self-contained session exports.
//!
//! This module generates standalone HTML files from coding agent session transcripts.
//! The exported files are:
//! - **Self-contained**: All critical CSS/JS inlined for offline operation
//! - **Progressive enhancement**: CDN resources enhance but don't break offline view
//! - **Encrypted (optional)**: Web Crypto compatible encryption for sensitive content
//! - **Accessible**: Semantic HTML with proper ARIA attributes
//!
//! # Architecture
//!
//! ```text
//! html_export/
//! ├── mod.rs           # Module facade (this file)
//! ├── template.rs      # Core HTML template generation
//! ├── styles.rs        # CSS (critical inline + Tailwind CDN fallback)
//! ├── scripts.rs       # JS (decryption, search, theme toggle)
//! ├── renderer.rs      # Conversation -> HTML rendering
//! ├── filename.rs      # Smart filename generation
//! └── encryption.rs    # Web Crypto compatible encryption
//! ```
//!
//! # Usage
//!
//! ```rust,ignore
//! use cass::html_export::{HtmlExporter, ExportOptions};
//!
//! let exporter = HtmlExporter::new();
//! let html = exporter.export_session(&session, ExportOptions::default())?;
//! std::fs::write("session.html", html)?;
//! ```
