GitLab's all-remote design system: a soft-purple-tinted neutral ramp (#3a383f text, #fbfafd subtle bg), #1f75cb confirm blue, semantic constructive/destructive color rules, GitLab Sans (Inter-derived) type at 14px, compact 4px-radius components, and a fully token-driven light/dark pair published as CSS custom properties in GitLab UI.
Primary actionThe merge-request widget aesthetic: stacked white panels with hairline #dcdcde borders, status icons in semantic green/orange/red circles, and one #1f75cb 'Merge' confirm button — CI state rendered as calm, bordered lists.
