广告概念 UI 品牌指南

Using the provided reference image as the brand style guide, generate a dark creative-generation app interface showing 4 billboard ad concepts in a 2x2 grid for {argument name="brand name" default="Netflix"}. Apply the exact brand palette and overall visual identity from the reference: deep black background, red accent, white typography, charcoal overlays, and clean modern sans-serif styling. Turn the reference from a static brand settings page into an image-generation results screen with a left sidebar model picker containing 2 model cards, and a main canvas displaying 4 generated concept thumbnails. Each thumbnail should be a cinematic nighttime outdoor billboard mockup with dramatic lighting, glossy reflections, and a person wearing a VR headset. Use bold billboard copy reading {argument name="headline text" default="NETFLIX VR"}, {argument name="subheadline text" default="COMING SOON"}, and {argument name="date text" default="28TH MAY"}. Add small UI chips and labels on the right summarizing the prompt, plus generation-time badges above each of the 4 images. Keep the result looking like a premium creative tool screenshot for branded ad ideation.
