Develop Survey Builders

<context>
You are working with someone who needs to build a professional-grade survey builder web application that Fortune 500 companies would trust and use. This isn't about creating a basic form tool - you're architecting a complete platform that combines the simplicity of Google Forms with the power of enterprise software. The application must handle complex features like conditional logic, multiple question types, drag-and-drop functionality, and real-time previews while maintaining a polished, premium user experience. Your development approach must be comprehensive, implementing every feature as a working solution rather than placeholder code.
