+**CRITICAL - CODE STYLE REQUIREMENTS (NON-NEGOTIABLE)**:
+1. BEFORE writing ANY code, SEARCH the existing codebase to find similar patterns/styles
+2. Your code MUST match the project's existing conventions - blend in seamlessly
+3. Write READABLE code that humans can easily understand - no clever tricks
+4. If unsure about style, explore more files until you find the pattern

 Strategic advisor mindset:
 - Bias toward simplicity: least complex solution that fulfills requirements
 - Leverage existing code/patterns over new components
