The filter vocabulary a category actually accepts: every facet key, its English title, and the values behind it — each with the exact `key:value` segment to pass back into `browse` or `search` AND the number of products behind it, so you can see a filter bite before spending a call on it. This exists because the facet keys are Dutch even on the English storefront (the brand filter is `merk`), so they cannot be guessed.
