The system this console is built in
1. One palette, shared with the top page

The console reads the same base scale as the top page, the gallery and the blueprint. Its own names — card, primary, destructive — are aliases onto that scale, not a second palette.

2. Sans for the interface, mono for the data

Labels, headings and buttons are set in the product's sans. JetBrains Mono is kept for what it is good at: metric values, log lines, route paths and anything with tabular numbers (font-feature-settings: 'tnum' 1, 'zero' 1).

3. Status colour is not brand colour

Nominal, warning and error each own a hue and nothing else uses it. The brand orange is reserved for actions, so a healthy metric can never be mistaken for a button.

4. 62 systems, none of them near each other

Every one of the 62 design systems this server ships is checked so that no two palettes come within 0.55 of each other in OKLab, in both colour modes. The closest pair measures 0.581.
