GitHub's surface is engineered, not decorated. Every pixel announces a stance: this is a tool for people who care about diffs, builds, and pull requests. The page background is a clean `#ffffff` (light) or `#0d1117` (dark), with content arranged on dense rectangular panes separated by hairline borders rather than negative space. Information density is the brand — list rows, code lines, repository headers, and notification cards are all packed close together so a power user can scan a hundred items without scrolling.
