Start with a topic or an audience. At launch the catalog is small, so this is the simplest way in. The full filterable library comes in a later phase.
Phase 1. With 8-10 products at launch, a full filter rail (price, format, type, age) would sit mostly empty, so we lead with topic and audience instead, which is also how people tell us they search. When the catalog grows, the full filterable library (shown as a reference) becomes the primary browse.
