123Stat block

One number at display scale, with what it measures and where it came from. The source line is structural, not optional — a stat with no attribution visibly collides with the next paragraph.

Use it for

A figure the argument turns on
Benchmark results, survey findings, limits

Not for

Several numbers — that is a Stat band or a Table
A number you cannot source. The design will make that obvious, which is the point

Inline

markup

<figure class="ns-statblock ns-statblock--stack">
  <span class="ns-statblock__figure">6MB</span>

</figure>

Accessibility contract

Tabular numerals, so a column of these aligns
The figure and its label are separate elements, so the number is never read without its unit
