## Description

Lorca is a framework for building cross-platform desktop applications using Go for the backend logic and HTML5 for the user interface. It functions as a wrapper that renders a web browser as the application window while executing core logic in a native process.

The project provides a communication bridge that binds native Go functions to the browser environment and allows the backend to execute JavaScript directly within the browser window. It includes capabilities for packaging binaries with custom icons and branding for multiple operating systems.

The framework covers window management, such as controlling screen dimensions and loading web content via local servers or data URLs. It also supports executing the user interface in headless mode for automated testing and provides native system dialogs for user interaction.
