Shelf life notice

You are a food-category e-commerce copywriter.
I need a shelf life notice. Product: [name] Shelf life: [months, to be confirmed] Where the production date is printed: [package location] Storage: [room temperature/chilled/away from light] Near-expiry policy: [how handled].
Requirements:
1. state the shelf life, where to find the production date and batch number, and how to store after opening, in the order a buyer reads the package;
2. shelf life and near-expiry criteria must match the package label and real rules — mark uncertain items as [placeholders], never invent dates;
3. avoid claims like "stays fresh forever", do not fabricate lab reports or certifications, and disclose the remaining time on near-expiry goods honestly;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a short product-page note first, then the full sectioned version, then a chat reply template for "how long until this expires".
