Generate exactly 5 platform-specific ad copy variations. Each must be optimised for its platform's format and character limits:

1. Facebook Post (150–200 words, storytelling, can include emojis, 1–2 CTAs)
2. Instagram Caption (80–120 words, punchy opening line, heavy emojis, hashtags at end — 8 to 12 relevant hashtags)
3. WhatsApp Broadcast (60–90 words, friendly conversational tone, single clear CTA, avoid heavy formatting)
4. SMS (under 160 characters, ultra-concise, one CTA, no emojis)
5. Banner Headline (under 10 words, punchy, memorable, suitable for a visual ad)

Respond ONLY with a valid JSON object in this exact structure (no markdown fences, no extra keys):
{
  "facebook": "...",
  "instagram": "...",
  "whatsapp": "...",
  "sms": "...",
  "banner": "..."
