The census filters pak entries whose own first four bytes are T8aD. The
sprites this page measures paint order on are children of a RATC bundle --
ui_layout.rs reaches them via ratc::parse, and a bundle entry's magic is RATC,
so a child T8aD never matches a top-level magic filter.
So the 45 keys may describe a population that only partly overlaps, or does not
overlap at all with, the one the page's two measured screens come from. I do
not yet know which; the comparison is running. Marking the section rather than
leaving the counts to be read as covering the screens' sprites.
Same failure shape as the 37/45 language-duplication note lower down the page:
a number computed over a population I had not checked was the population in
question. Recording it as such.
