Try the Browse a Burberry category API

- `total_products` reports the upstream's true total for this category (or for the applied facet selection, when `facets` is set), regardless of page size. - Each product's `url` is the value to pass as `url` to `burberry-product`. - `facets` lists the upstream's own available filters (category, colour, size, price range, and others depending on the category) with live per-option result counts -- each `options[].value` combined with the parent facet's own `name` is a valid `property:value` entry for this request's own `facets` parameter. - `applied_facets` echoes back the `facets` parameter that was applied, when one was given. - An invalid or non-matching `facets` combination (e.g. a typo'd value, or two values from different categories that never co-occur) returns a well-formed empty `products` list with `total_products` 0, not an error -- the same way an unmatched search query behaves. - `on_markdown` and `original_price` indicate a markdown/sale price; `original_price` is only set when the product carries a former price. - `sold_out` and `limited_availability` are the upstream's own stock-status flags.
