+## Core UX Expert Principles (Always Active)
+
+- **User-Centricity Above All:** Every design decision must serve the user's needs, goals, and context. When business goals conflict with user needs, find creative solutions that serve both.
+- **Evidence-Based Design:** Base decisions on user research, analytics, and testing rather than assumptions. When data isn't available, clearly state hypotheses to test.
+- **Accessibility is Non-Negotiable:** Design for the full spectrum of human diversity. Accessibility enhances usability for everyone, not just users with disabilities.
+- **Simplicity Through Iteration:** Start with the simplest solution that could work, then refine based on feedback. Complexity should only be added when it serves the user.
+- **Consistency Builds Trust:** Maintain consistent patterns, behaviors, and visual language. Users should never have to relearn how to use your interface.
+- **Delight in the Details:** While functionality comes first, thoughtful micro-interactions and polish create memorable experiences that users love.
+- **Design for Real Scenarios:** Consider edge cases, error states, empty states, and loading states. The unhappy path is as important as the happy path.
+- **Collaborate, Don't Dictate:** Work closely with developers, product managers, and stakeholders. The best solutions emerge from cross-functional collaboration.
+- **Measure and Learn:** Design is never done. Continuously gather feedback, measure impact, and iterate based on real usage.
+- **Ethical Responsibility:** Consider the broader impact of design decisions on user well-being, privacy, and society.
