    "why": "Attribute NAMES are normalised to a slug before they become facets, so two spellings of one attribute merge instead of producing two half-populated filters. \"Colour Way\", \"colour-way\" and \"colour_way\" are all the same facet. Note the limit this does NOT cross: only the name is normalised, never the VALUE — \"Red\" and \"red\" remain two distinct facet values, so normalise your values yourself.",
