  Optional JSON-LD fragment for Offer list / strikethrough price (Google Merchant / ads).

  Accepts:
  - variant: {Object} required
  - product: {Object} required (for price_visibility check)

  When product.metafields.custom.price_visibility has a value:
  - ListPrice prefers variant.custom.amazon_ebay_price (MAP), then product-level same key,
    then Shopify compare_at_price only as fallback.
  - Omitted if no list value or list price is not greater than variant.price.

  Parsing notes:
  - Do not call money_without_currency on plain text MAP values first; Shopify can return a
    partial fragment (e.g. from "89.990"), which parses tiny, fails sanity, and falls back to compare_at.
  - Money JSON: use .amount / guarded .amount_cents first; money_without_currency only for money type.
  - String / single-line MAP (e.g. "89.990"): coerce via strip + remove $/commas + plus (never value|plus on Money drops).
