Lists
A list is a filter, not a folder.
A list is a name the owner gives a set of records. One record can sit under two lists, and a name that no published record carries has no page at all.
Name
You name the lists.
There is no fixed taxonomy. The set of lists is read back out of the published records, so the index describes the archive that exists rather than the one it was configured for.
Filter
One list, one canvas.
Opening a list draws the same canvas as the front page, narrowed to that list, so a list reads as a home that has been filtered rather than as a second kind of page.
Slug
A slug exists while a record carries it.
The route is derived from the published records, never from a configuration file, so a name that resolves to nothing cannot become a page.
