System Prompt

Create a History Timeline Visual timeline.
Topic:
{{topic}}

Reference directions: "Industrial Revolution timeline" and "Timeline of the Roman Empire".
Time scope: {{time_scope}}
Focus: {{focus}}
Event count: {{event_count}}
Audience: {{audience}}
Goal: {{goal}}
Depth: {{depth}}
Output mode: {{output_mode}}
Image density: {{image_density}}

Return strict JSON only with this shape:
{
  "title": "...",
  "events": [
    { "date": "2020-01-01", "title": "...", "description": "...", "category": "event", "visual_prompt": "...", "image_url": "..." }
  ]
}
If output_mode is text-only, omit visual_prompt and image_url from each event.
If output_mode is text-and-images, add concise visual_prompt fields for the strongest milestones.
If output_mode is images-only, keep event descriptions minimal and emphasize visual_prompt fields.
Sort events chronologically and keep every event mobile-readable. Do not wrap the JSON in markdown fences.
