Topic or brief:
{{topic}}

Reference directions: "Stoicism in 5 cards" and "Plato’s cave visual summary".
Audience: {{audience}}
Tone: {{tone}}
Slide count: {{slide_count}}
Output mode: {{output_mode}}
Image density: {{image_density}}

Return strict JSON only with this shape:
{
  "title": "...",
  "slides": [
    { "layout": "title", "title": "...", "subtitle": "...", "image_prompt": "...", "image_url": "..." },
    { "layout": "default", "title": "...", "content": [
      { "type": "text", "content": "..." },
      { "type": "bullets", "content": "bullet one\nbullet two\nbullet three" }
    ], "image_prompt": "...", "image_url": "..." }
  ]
}
If output_mode is text-only, omit image_prompt and image_url from every slide.
If output_mode is text-and-images, include strong image_prompt text for the title slide and each content slide.
If output_mode is images-only, keep copy minimal and rely on image_prompt to drive the deck.
Keep slides concise, swipeable, and easy to scan on a phone. Do not wrap the JSON in markdown fences.
