Wildcard re-exports obscure each slice public surface and weaken
tree-shaking. Convert to explicit named re-exports with export/export
type split (B-1) for ComparisonView, ChangeAppTheme, Breadcrumb/model,
and FilterAndSortFonts/api barrels.
Breadcrumb is not a business aggregate — it is a scroll-tracking navigation
capability (NavigationWrapper registers page sections into a store), so it
belongs in the features layer, not entities. Move the whole slice and
repoint its three widget consumers. entities/ now holds only Font, a true
aggregate.
