AI Generation (When Needed)

Only use when:

• Custom branded illustration required
• No suitable free resource exists
• User explicitly requests

// DALL-E 3
const response = await fetch('https://api.openai.com/​v1/​images/​generations', {
  method: 'POST',
  headers: { 'Authorization': `Bearer ${OPENAI_API_KEY}` },
  body: JSON.stringify({
    model: 'dall-e-3',
    prompt: 'Minimal 3D illustration of [concept], soft gradient background, no text',
    size: '1792x1024',
    quality: 'hd',
  }),
});
