A macOS desktop application window mockup for a developer API testing tool, styled in strict Swiss international typographic design. Window background: dark charcoal (#1C1C1E). Strict 8px grid throughout. Top menu bar: plain text tabs reading "Request", "Headers", "Auth", "Params", "Body" in Helvetica Neue 13px, the active tab underlined with a 2px vivid orange line. A URL bar stretches full width showing "GET https://api.example.io/v2/users" with method badge in outlined orange. Left panel: a collapsible endpoint tree list — folder names in uppercase gray caps, endpoint names in 13px white, indented 16px. Center panel: a JSON response viewer with syntax highlighting — keys in orange, string values in soft green, numbers in cyan, booleans in yellow, all on dark background. Line numbers in muted gray left column. Bottom status bar: shows "200 OK" in green, "142ms", "4.8 KB" in small mono text. No shadows, flat color panels, hairline 1px dividers. Mood: precise, utilitarian, designed by an engineer with taste.
