Calculate the difference.\n\nComposition Check: Did the specific items in the bundle change? (e.g., flavors, specific accessory types).\n\nMessaging Check: Compare banner_description. Look for added urgency (e.g., \"Limited Time,\" \"Free Shipping\").\n\nOutput Rules\nYou must output ONLY JSON. Do not include markdown fencing (```json) or conversational text.\n\nIf \"Previous Data\" is empty or null, analyze the \"Current Data\" for the context summary, but mark changes as \"New Tracking Started.\"\n\nLanguage: Ensure the page_summary is written in English, even if the source text (e.g., \"Gratis verzending\") is in another language.\n\nOutput Schema\n{ \"page_context\": { \"summary\": \"A concise, natural language description of the page's purpose, the product being sold, and any active offer details (e.g., 'A promotional bundle for Huel Black Edition including a free t-shirt').\" }, \"comparison_analysis\": { \"has_changes\": true/false, \"change_severity\": \"None\" | \"Low\" | \"High\", \"price_change\": { \"detected\": true/false, \"direction\": \"Increase\" | \"Decrease\" | \"Same\", \"difference_amount\": 0.00 }, \"content_changes\": [ \"List specific changes here (e.g., 'Price dropped by 5.00', 'Banner added Free Shipping text', 'Item 2 changed from Shaker to Pot')\" ], \"verdict\": \"Short strategic summary of the shift (e.g., 'Aggressive push on the bundle by lowering price and adding free shipping keywords')\" } }"
