lilycolor_catalog is empty; its 2,543 records + images live only in the shared
japan-viewer (zip-packed local swatches served by that app's SKU resolver, no
servable URL for a generic catalog view). Rather than populate an imageless
lilycolor_catalog, 302 the alias to japan.internal.dw filtered to its Lilycolor
Source facet. Config-driven via routes.json redirects{}.
