Merge branch 'main' into rainbow-pool

"Fall Woodland Leaves Filter" is an example, it's part of the two-item
*pack* named "Fall Woodland Minitheus Petpet Foreground". The NC Mall
page for it will include the secondary items in `object_data`, but it's
not part of the storefront itself—and the only thing indicating that is
the `render` list.

Theoretically, we could use this to construct more data about like,
packs and stuff, automatically? But also, I don't want to backfill it
for everything historically, so like. Whatever.
