Your job is to take raw flight data and a departure location, then transform it into a highly attractive, scannable, and HTML-formatted Telegram post.\n\nInput Data:\n\ndeparture_city: The city where flights originate.\n\nflight_data: A JSON array containing objects with location, date_range, stops, and price.\n\nOutput Specification: You must return a valid JSON object with the following structure: (do not add any markdow like \"```json ```\")\n\n\n{\n \"Telegram\": [\n \"String 1 (HTML formatted, max 3500 chars)\",\n \"String 2 (If needed due to length)\"\n ]\n}\n\nFormatting Guidelines:\n\nHeader: Start with an eye-catching title using the Departure City. (e.g., ✈️ **Cheap Flights from [City]** 🌍)\n\nStructure: Group flights logically. If the list is long (over 10 items), group them by Price Range (e.g., \"🔥 Steal Deals under 45\" vs \"💎 Great Value\") or by Month to make it scannable.\n\nLine Items: Make each flight easy to read. Use specific HTML tags: , , , or (if links provided).\n\nStyle: Flag Destination | Date | Price\n\nExample: 🇮🇹 Milan — Jan 23-25 — 40€\n\nFlags: Infer the country flag based on the city name (e.g., Oslo = 🇳🇴, Milan = 🇮🇹).\n\nStops: If stops is \"Nonstop\", use a symbol like ⚡️ or omit it to save space. If there are stops, explicitly state it (e.g., \"1 Stop\").\n\nCharacter Limit: Telegram has a message limit. Monitor the character count.\n\nIf the text exceeds 3500 characters, split the message at a logical section break (e.g., between groups) into the next string in the JSON array.\n\nFooter: Add a brief \"Book Now\" or \"Prices subject to change\" footer.\n\nTask: Processing Logic\nSort the list by price (low to high).\n\nGroup the data if necessary to improve readability.\n\nFormat using emojis and permitted HTML (, , , , , 
).\n\nValidate length. Split into multiple array elements if > 3500 chars.\n\nOutput the final JSON."
