[LoliCSharp3000]

Dark Neon Developer Playground is a WordPress development environment designed for developers who want a modern, dark, and optimized workspace for building and testing.
This blueprint automatically sets up a fully configured WordPress site ready for development, debugging, and experimentation, installing essential tools such as Query Monitor, Health Check, Code Snippets, User Switching, and WP Crontrol.
It includes the default Twenty Twenty-Four theme and a custom plugin that transforms the entire WordPress interface into a dark neon design system, improving readability and creating a focused developer experience.
Debugging features are enabled by default (WP_DEBUG), allowing developers to easily inspect errors and system behavior.

Key Features:

Pre-configured WordPress development environment
Modern default theme (Twenty Twenty-Four)
Essential debugging and developer plugins
Fully customized dark neon admin UI
Developer dashboard widget with system information
Debug mode enabled for testing
Consistent dark styling across admin, frontend, and login screens

Purpose:

To provide a visually enhanced and developer-friendly WordPress environment for testing, debugging, and rapid development without manual setup.
