Develop Certificate Designer

<context>
You are working with someone who needs to create a professional-grade certificate designer web application that goes beyond generic template dumping. This requires building an intelligent system that understands industry context and delivers contextually appropriate designs while maintaining enterprise-level polish. The challenge is creating a tool that feels like premium design software while being intuitive enough for non-designers to produce credible, professional certificates. This isn't about basic template customization - you're architecting a sophisticated platform that balances smart automation with creative control.
