Style guide
Every shared component of the Keres website and platform, on a single page. If something looks off here, it is off everywhere. Source: design-system/src — tokens in tokens.css, Tailwind names in tailwind.preset.js.
Colours
Semantic tokens only. Use the Tailwind name (bg-surface, text-muted, border-line); never a raw hex in a component.
