Extendable is a dynamic block theme built for the full site editing (FSE) environment. It serves as a flexible starting point for developers and site builders creating new websites that utilize the block editor for site-wide design. The theme is designed to be a clean canvas that is highly adaptable through its built-in style system.

• Multiple Style Variations: Switch between distinct visual presets—like fresh, bold, bohemian, or minimal—instantly. This allows for rapid prototyping and design changes without custom code.
• Built for Full Site Editing: The theme is structured to work natively with the block editor's site editing features, providing a cohesive experience for designing headers, footers, templates, and global styles.
• Developer-Friendly Foundation: As an open-source project hosted on GitHub, it provides a transparent codebase for customization. It includes tooling for code linting and standards checks to maintain code quality.
• Expressiveness and Flexibility: Described as an expressive theme, it provides a strong foundational design that can be extended and personalized using the standard block editor tools and global styles interface.
