// LinkedIn post generator using OpenAI
  async function generateLinkedInPost(topic, tone = 'thought-leader') {
  const systemPrompt = `You are a LinkedIn ghostwriter. Write posts that:
  - Open with a strong hook (1-2 short lines)
  - Use short paragraphs (1-2 sentences each)
  - Include line breaks for readability
  - End with a question or call to engage
  - Tone: ${tone}`;

  const response = await fetch('https://api.openai.com/v1/chat/completions', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.OPENAI_API_KEY}`,
