Tool: Gemini Nano Banana 2
Objek target: Ilustrasi 3D isometrik mobil sport coupe, body hitam midnight, velg gold multi-spoke, jendela tinted dengan refleksi biru-teal, latar belakang putih solid #FFFFFF, tanpa ground plane atau elemen lain.
Prompt ditulis sebagai satu paragraf narasi biasa.
Generate a single 3D isometric illustration of a sleek modern sports car, viewed from a front-left elevated angle at 45 degrees. The car should be a stylized coupe silhouette inspired by Mercedes-Benz or BMW, not a real licensed model. The body is deep midnight black with subtle dark navy undertones. Rims are multi-spoke gloss gold. Windows are dark tinted with a very subtle blue-teal reflection. Headlights emit a soft cold white glow. The surface has smooth matte finish with very gentle specular highlight along the roofline and hood. No hard shadows on the car body itself. A very soft diffused shadow pool sits directly beneath the car. Background is plain solid white #FFFFFF. No ground plane, no floor texture, no environment, no scene, no text, no labels. The car is centered with equal margin on all sides. Style is clean editorial 3D render, similar to a product shot for a luxury brand campaign. Smooth surfaces, no photorealism, slightly stylized proportions. Output as a single isolated object on white background.

Objek target: Premium car marketplace mobile app — dark luxury theme, React + Tailwind CSS, responsive mobile & desktop, 5 halaman utama (Home, Browse, Detail, History, Profile).
Prompt ditulis sebagai deskripsi naratif panjang dalam satu blok teks.
Build a premium car marketplace mobile app UI using React with Tailwind CSS.
App Overview:
A modern luxury-feel car buying and selling app featuring Toyota, Mercedes-Benz, Ford Mustang, BMW, and other brands. Similar to a premium version of OLX or CarGurus.
Design System:
Typography uses Bebas Neue or Barlow Condensed for headings and DM Sans for body text, imported from Google Fonts. Color palette: background #0D0D0D deep black, surface cards #161616 and #1E1E1E, primary accent #C8A96E warm gold for luxury feel, secondary accent #E8E8E8 light silver, CTA highlight #FF4C29 red-orange for buttons, primary text #FFFFFF, muted text #888888, success green #22C55E. Visual style is dark luxury automotive theme with glassmorphism cards with subtle gold border, smooth rounded corners 16 to 24px radius, subtle grain texture on background, gradient overlays on car images fading to black at bottom, and bold wide-spaced typography on headings.
Responsive Behavior:
On mobile under 768px use full screen layout with fixed bottom navigation bar containing four tabs Home, Browse, History, and Profile. Bottom nav has gold active indicator dot and safe area padding for notch devices. On desktop 768px and above use sticky top navbar with logo on left, nav links in center, and CTA button on right. Desktop uses 3-column grid for car listings.
Pages and Screens:
Home Screen includes a hero section with full-width featured car image with gradient overlay showing car name in large bold type with price and View Details button. Below that is a horizontal scrollable brand filter with pills for All, Toyota, Mercedes, BMW, Mustang, Porsche, and Lamborghini. Then sections for Hot Deals, Recently Viewed, and Popular in Your City as horizontal scroll cards. Each car card shows image, brand logo badge, car name, year, price, mileage, and fuel type.
Browse Screen has a search bar at top with mic and filter icons, filter chips for Price Range, Brand, Year, Fuel Type, and Condition, and sort options for Newest, Price Low to High, and Most Popular. Car listings show in 2-column grid on mobile and 3-column on desktop with image, bookmark icon, brand badge, name, specs, and price.
Car Detail Screen shows full-bleed hero image with back, share, and bookmark buttons and a swipeable image gallery. Below shows car name in large heading, year badge, condition badge, price with Best Price Guarantee label, and a quick specs row for Engine, Transmission, Mileage, and Fuel. Tabs for Overview, Specs, Reviews, and Similar Cars. Seller info card shows avatar, name, verified badge, and response rate. Sticky bottom bar has Chat Seller and Buy Now buttons.
History Screen has tabs for Viewed, Inquired, and Purchased. Shows timeline list with car thumbnail, name, date, and status badge. Status badges are Ongoing in yellow, Completed in green, and Cancelled in red. Includes empty state with illustration.
Profile Screen has a hero card with avatar, name, member since date, and verified badge. Stats row shows Cars Viewed, Inquiries Sent, and Purchases. Menu items include My Listings, Saved Cars, Payment Methods, Notifications, Help and Support, Privacy and Security, and a dark mode toggle. Logout button in subtle red at bottom.
Components to build include BottomNav with blur backdrop and gold active dot, TopNav that is transparent on top and solid on scroll, CarCard as dark glass card with image on top and specs below, BrandPill as scrollable filter chips, HeroSlider with gradient overlay, SpecBadge as small icon and text pill, StatusBadge as colored pill, and StickyBookButton as floating CTA on detail page.
Animations include car cards scale up on hover to 1.02, bottom nav icons bounce on tap, hero image subtle parallax scroll, page transitions slide in from right, and skeleton loading placeholders for images.
Tech stack is React with functional components and hooks, Tailwind CSS, placeholder images from unsplash for car and luxury queries, lucide-react for icons, and hardcoded mock data for 8 to 10 cars with no backend needed.
Avoid generic white backgrounds, boring flat cards, system fonts, overcrowded layouts, and purple gradients.
