A 1px divider in `--line`, the pack's one hairline colour. `strong` steps to
`--ink-soft` rather than inventing a second line token — the palette is three
colours and a fourth would mean one of them stopped meaning something.

Reach for it rarely. This pack separates things with the field between slabs and
with `44px` of space inside them; a rule that is doing decorative work is a gap
that was measured wrong.
