       Design tokens

       The palette is neutral by design: zinc greys carry the whole page and the
       only saturated colour is status (green / amber / red), which is the thing
       a monitoring product actually needs to signal. There is no chromatic brand
       accent — "accent" here means the CTA colour, which is near-black on light
       and near-white on dark, so --accent-fg has to travel with it wherever a
       rule paints text on an accent background.
