Table columns, detail rows, the status bar, the sidebar and the
dashboard widgets showed dates, counts, enum words and labels in the
monospace face. They now use the UI face (sk-cell-dim for dim table
cells); monospace stays on hosts, IPs, ports, versions, paths, IDs,
hashes, code and logs. check-type-scale ratchets the number of
monospace rules so it only goes down.
Core SCSS used about 30 font sizes (9, 9.5, 10.5, 11.5, 12.5px...)
and six weights, so the same kind of text looked different on every
page. It now uses -xs..2xl (12, 13, 14, 16, 18, 24, 32px) and
three weights, following the dense-product norm: 14px body and a
12px floor, as in Primer, Carbon and Atlassian, which raised its own
minimum from 11px to 12px for legibility. Small labels that were
9-11.5px grow to 12px.
The old $font-size-* names stay as aliases on the new scale so
extension stylesheets keep compiling; check-type-scale rejects them,
raw sizes and off-scale weights in core.
