+title: "PACE: Pattern for Agentic Conversational Experience"
+abstract: >
+  PACE is a design framework for guide-first interfaces where AI leads users 
+  through conversation rather than traditional navigation. The acronym works 
+  on two levels: as "Pattern for Agentic Conversational Experience" (the what) 
+  and as four behavioral principles—Proactive, Adaptive, Contextual, Efficient 
+  (the how). PACE inverts the traditional browse-and-hunt paradigm, placing 
+  an AI guide at the center of the user experience.
