Please generate scene outlines based on the following course requirements.

User Requirements

{{requirement}}

{{userProfile}}

Language Context

Infer the course language directive by applying the decision rules from the system prompt. Key reminders: - Requirement language = teaching language (unless overridden by explicit request or learner context) - Foreign language learning → teach in user's native language, not the target language - PDF language does NOT override teaching language — translate/explain document content instead

Output Requirements

Please automatically infer the following from user requirements:

• Course topic and core content
• Target audience and difficulty level
• Course duration (default 15-30 minutes if not specified)
• Teaching style (formal/casual/interactive/academic)
• Visual style (minimal/colorful/professional/playful)

Then output your response as a single JSON object.

Top-level shape — this is what you MUST return:

{
  "languageDirective": "2-5 sentence instruction describing the course language behavior",
  "courseTitle": "concise course name, ≤30 chars, in the teaching language",
  "outlines": [ /* array of scene objects, schema described below */ ]
}

Never return a bare array. Never omit languageDirective or courseTitle. All three keys are required.

Each scene inside the outlines array has this minimum shape:

{
  "id": "scene_1",
  "type": "slide" | "quiz" | "interactive" | "pbl",
  "title": "Scene Title",
  "description": "Teaching purpose description",
  "keyPoints": ["Point 1", "Point 2", "Point 3"],
  "order": 1
}

Special Notes

• quiz scenes must include quizConfig: json "quizConfig": { "questionCount": 2, "difficulty": "easy" | "medium" | "hard", "questionTypes": ["single", "multiple"] } {{#if hasSourceImages}}
• If source images are available, add suggestedImageIds to relevant slide scenes. Only use image IDs listed under Available Images. {{/if}}
• Interactive scenes: If a concept benefits from hands-on simulation/visualization, use "type": "interactive" with widgetType and widgetOutline fields. Limit to 1-2 per course.
• Select widgetType based on concept: simulation (physics/chem), diagram (processes), code (programming), game (practice), visualization3d (3D models)
• Provide appropriate widgetOutline for the widget type
• Scene count: Based on inferred duration, typically 1-2 scenes per minute
• Quiz placement: Recommend inserting a quiz every 3-5 slides for assessment
• Language: Infer from the user's requirement text and context, then output all content in the inferred language
• If web search results are provided, reference specific findings and sources in scene descriptions and keyPoints. The search results provide up-to-date information — incorporate it to make the course content current and accurate.

Final reminder: your entire response must be a JSON object with exactly three top-level keys — languageDirective (string), courseTitle (string, ≤30 chars, in the teaching language), and outlines (array). Do not return a bare array. Do not wrap in prose or code fences.
