- evo_megamenu_json stays project-neutral: new panel layout "catalog";
for such entries the MenuBuilder dispatches the new PSR-14 event
BuildCatalogEvent and emits whatever a listener sets as `catalog`
(null without a listener). The entry's teaser cards serve as the
featured tiles; the teaser inline field now also shows for "catalog",
and the entry form reloads when the layout changes. README section
"Layout catalog"
- VITEC listener ProvideProductCatalog fills it, modelled on the Ross
Video products menu: main categories below the "Product" root, their
subcategories as groups, products with a plain-text one-line teaser;
same visibility rules as the product list, Product Finder links
(/products?cat=&subcat=), empty categories and groups left out, three
queries for the whole catalog
- Product type-ahead GET /_json/?type=7385&q= (USER_INT page type,
ProductMenuSearchJsonRenderer): Solr restricted to products, last term
completed as a prefix, up to six product cards plus their titles as
autocomplete suggestions; endpoint announced in catalog.search
- Spec v1.23 (clause 7.16: product type-ahead)
