A pixel-perfect desktop vector design tool interface in dark mode, resembling a professional vector editor. The application chrome is very dark gray (#1A1A1A). The left sidebar contains tool icons: select, pen, rectangle, ellipse, text, image, and hand tools — all in a compact vertical strip. The center canvas area has a medium dark (#242424) background with a subtle dot grid. On the canvas sits a logo-design project: a stylized "A" letterform being constructed with bezier curves and anchor points visible (blue dots and handles). The right-side properties panel shows: Fill (solid coral #FF6B6B), Stroke (none), Width "82px", Height "96px", Corner radius "0", Opacity "100%". The layers panel (collapsed in left panel accordion) shows layer names: "Frame 1", "Logotype", "Guides" — "Logotype" is highlighted. A toolbar at the top shows file name "BrandKit — v3" and "Share" + "Export" buttons on the right.
