I have a large codebase that I want to understand better through visual architecture diagrams. Please analyze the project structure and create comprehensive Mermaid diagrams that help me understand the codebase at different levels of detail.

📋 Required Analysis

First, explore the codebase to understand:

1. Project structure - root directories, main modules, configuration files
2. Dependencies - internal dependencies between modules/packages
3. Architecture patterns - layered architecture, microservices, monolith, etc.
4. Key systems - core functionality areas (UI, backend, database, API, etc.)
5. Technology stack - frameworks, languages, tools used

Overview

This report details my contributions to enabling master page copying in LibreOffice Impress, addressing a 13-year-old bug (Bug 45617) that prevented users from duplicating master page templates. My work, delivered through two Gerrit patches (Change 179832 and Change 182206), was integrated into LibreOffice 25.8.0, released in 2025. The changes involved refactoring a complex codebase and implementing robust master page copying functionality, significantly improving Impress’s usability for creating presentation templates.
