Use case: stylized-concept. Asset: premium editorial cover illustration for a Blockstream Enterprise custody committee briefing. Create an original architectural exploded drawing of exactly five thin rectangular review frames with aligned rectangular apertures. A single cobalt-blue transaction path passes through the five openings. Three-quarter isometric view. The five plates represent treasury, security, operations, engineering and legal review converging on one decision. This is a conceptual editorial metaphor, not real hardware or a deployed product architecture. Make the geometry coherent: consistent perspective, open apertures, convincing edge occlusion, precise join details. Sophisticated engineering illustration with flat graphite planes and fine pale-gray line work, deliberate depth, and one strong centered composition. Landscape 3:2. Entire background uniform #111316. Planes #1E2024, edges white or pale gray, only accent #0066FF for the path. Generous clear margins, use most of the central canvas. No text, letters, numbers, logos, watermarks, UI, coins, locks, shields, people, ambient grids, random decorative marks, glow, gradients, glossy surfaces, glass, chrome or stock 3D blobs. Crisp publication-quality drawing that remains clear at the size of a report cover.
