Plan step 23, containment.md § Missing ("Divider: the divider-with-text /
subheader configuration"). `<x-divider text="…">` draws the label at the
start and the rule running on from it, with the divider specs table's
geometry: 4dp between the words and the rule, 8dp right margin, 8dp
bottom margin. The label is M3's subhead — title-small in
on-surface-variant, the only subhead type M3 publishes (the rich
tooltip's specs), since the divider page names none. The words stay text
naming the group; only the rule is the separator.
