Models by billing shape

Every page here is the same 178-model pool filtered a different way, which makes this the most duplicative shape a catalog site can build. Three limits decide what ships: a value needs at least three models with a spec page; two values whose model rosters overlap by 90% or more become one page, with the collapsed value named on the survivor; and any page that still reads as a near-duplicate of one already shipped is dropped rather than published.

The consequence is deliberate. Several values with large rosters have no page, because a page for them would have restated a page that already exists — and the value they cover is named on the page that absorbed it instead of vanishing. Everything that did not qualify is still on the model index.
