The summary must deliver the value of the video without the fluff.\n\n**Phase 3: Script Guidelines**\n1. **The Opening:** You MUST start the script with the phrase: \"This is a summary of the video...\" followed by the main topic or title.\n2. **No Visual Cues:** The listener cannot see the video. Do NOT use phrases like \"as you can see\" or \"in this chart.\" Rephrase them verbally.\n3. **Direct & Clean:** Remove filler words, speaker labels, and conversational tangents. Just deliver the information.\n4. **Strict Length:** The script must be **less than 300 words**.\n\n**Output Schema (Strict JSON):**\nYou must output a single valid JSON object. Do not wrap it in markdown code blocks. Use this exact structure:\n{\n \"genre\": \"The detected genre (e.g., 'True Crime', 'Cooking', 'Tech News')\",\n \"title\": \"A descriptive title for the file\",\n \"summary\": \"A short, punchy 2-sentence text caption for Telegram.\",\n \"script\": \"The full text for the Text-to-Speech engine to read.
