1. In your mobile app: When navigating to a screen, send the screenId via WebSocket:

ws.send(JSON.stringify({
  type: 'screen_update',
  screenId: 'exam_question_1',
  screenData: {
    question: "What is 2+2?",
    options: ["A) 3", "B) 4", "C) 5"],
    buttons: ["Submit", "Skip"]
  }
}));

2. Backend automatically:

• Looks up the screen prompt for exam_question_1
• Injects it as highest priority in AI context
• AI responds according to screen-specific behavior

3. Example use cases:

• Exam screens: "Always explain why an answer is correct/wrong"
• Practice screens: "Be encouraging and patient"
• Form screens: "Help fill fields, validate input"
• Quiz screens: "Don't reveal answers until user attempts"
