Design a 3:4 vertical "OS-style portfolio" editorial poster for [Personal Portfolio / Design Agency / Brand Project / Creative Team]. Use a deep graphite black background overall to establish a professional workstation-like interface order, but do not copy any specific brand's OS interface. Set a very narrow status bar at the top, sequentially placing: Brand Name / Current City / Date / Time / Online Status. Set a project directory area on the left, occupying about 30%—35% of the frame, with 6—8 project names listed consecutively. Each project includes: a short title and a one-sentence achievement description of no more than 12 words. Present the only activated core project on the right, occupying about 50%—55% of the frame. Use a single high-impact full visual image as the main visual, which can be a person, product, space, brand result, or key project visual. Do not split it into a thumbnail grid. The currently activated project should be highlighted in the left directory using reverse color, underline, or a single accent color, and establish a clear correspondence with the right main visual through a thin path, fine line, or positioning relationship. Add third-level auxiliary information at the bottom: Project Year, Service Type, File Status. Typography system: Use compact geometric sans-serif for main titles; neutral sans-serif for directory descriptions; monospaced fonts for time, numbers, and status. Color palette limited to: Charcoal Black, Warm White, Cold Gray, and one project accent color [Signal Orange / Cobalt Blue / Acid Green / Cold Purple]. The accent color area should not exceed 6%. Overall vibe like: Creative studio backend, digital archive, cultural magazine cover, mature proposal system. Avoid: Mimicking computer screenshots, stacked windows, complex icons, neon code rain, uniform card arrays, multiple images of equal size, cheap tech aesthetics.
