## Description

This project is a plugin-based WYSIWYG document layout engine and rich text editor that uses Canvas and SVG for rendering. It functions as a collaborative editor utilizing conflict-free replicated data types to enable real-time synchronization across multiple users.

The system serves as an interactive form builder, allowing for the embedding of input controls such as checkboxes and date pickers directly into documents. It is designed for high-fidelity output, ensuring the visual representation during editing matches the final format for PDF and image exports.

The editor covers broad capabilities including print layout management for page sizes and margins, rich text authoring with typography and structured lists, and the integration of complex elements like dynamic tables and mathematical formulas. It also provides tools for document organization, such as tables of contents and watermarking.

The framework is built on a plugin architecture that allows for the extension of core behaviors and the customization of user interactions.
