Kastle AI is an enterprise-grade showcase for AI agents in mortgage lending and servicing. We shipped in 14 days in Framer, using an editorial serif, hairline rules, square corners, a neutral palette, translucent panels, and custom 3D loops. We built responsive from our component library and added semantic structure, focus states, contrast checks, and a 30 day post-launch optimization window. The client was thrilled and added a bonus.
