This commit syncs minor changes for the default theme from its active development repository to core.
This is a follow up to [52081], [52107], [52164], [52222], [52283], and [52335]. The two main changes introduce global padding to site content while still allowing content to be full-width, and re-organize block patterns into Core's existing categories.
