AI-First Design Specifications

Conversational Interface Architecture (Phase 10)

chat_interface:
  layout_priority: "70% screen real estate"
  ai_character: "Maya - Professional Marketing Assistant"
  conversation_patterns:
    - campaign_creation: "Natural language → 30-second results"
    - performance_analysis: "Contextual insights on demand"
    - list_management: "Automated workflow activation"
    - optimization: "AI-powered A/B testing setup"

Component Standards (shadcn/ui)

// Professional chat component architecture
interface ChatInterfaceProps {
  isTyping: boolean;          // Loading state management
  messages: ChatMessage[];    // Conversation history
  aiCharacter: 'maya';        // Consistent AI personality
  responseTime: '<2s';        // Performance standard
}

// Design token system
const designTokens = {
  colors: {
    primary: 'hsl(142 76% 36%)',      // Maya Green #22C55E
    foreground: 'hsl(222.2 84% 4.9%)', // Dark text
    background: 'hsl(0 0% 100%)',      // White background
  },
  spacing: {
    radius: '1.125rem',               // Border radius
    padding: '16px',                  // Container padding
  }
};

Animation Standards

Typing Indicators: Professional pulsing dots with "Maya is thinking..." text
Message Animations: Smooth slide-in effects with cubic-bezier timing
Loading States: Skeleton components and progress indicators
Micro-interactions: Hover states, focus rings, button feedback

Enhanced Quality Gates

Phase Validation Checkpoints

Phase 0: Prerequisites BLOCKING
