Technical Highlights

• OOP PHP architecture — Singleton main class, separated concerns (Settings, API Client, AJAX Handler)
• Security-first — Nonce verification, capability checks, input sanitization, output escaping
• Gutenberg native — Built with @wordpress/plugins, @wordpress/components, @wordpress/data
• Clean API abstraction — OpenAI client class with structured prompts and proper error handling via WP_Error
• WordPress Settings API — Full admin settings page with sanitization and whitelisted model selection
