Tables drop the hard 1px grid: a soft accent-tinted vertical gradient
header (overridable via --table-head-a/b), a very faint diagonal
--table-tint wash lifting the cells apart, and only a whisper of a row
separator. Definition lists become a lightweight two-column grid
(minmax term column, explicit grid-column placement so runs of
dt/dd stack right) with accent terms and no borders or fills. Tables
also join the bottom-margin-only spacing convention.
