Hybrid Routing

// Simplified routing logic
function routeQuery(query: UserQuery): 'client' | 'server' {
  // Check query complexity
  const complexity = analyzeComplexity(query);

  // Simple queries → Client

    // "cheaper", "warmer", "different color"
    return 'client';
  }

    return 'client';
  }

  if (complexity.isIntentClassification) {
    // Hover/scroll behavior analysis

  }

  // Complex queries → Server
  if (complexity.requiresMultiStep) {

  }

  if (complexity.requiresInventorySync) {
    // Real-time stock checks

  }

  // Default: server for safety
  return 'server';
