App screen test: Generate exactly these images with the image model you were given. Use each prompt word for word: do not rewrite, add to or "improve" it. Use the highest quality the tool offers and 2K if it offers a resolution. Aspect ratio 2:3 unless the prompt says otherwise. One generation per prompt; retry only if the call errors. Do not edit, crop or upscale the results. Deliver the images in order (01.png, 02.png, ...) and an index.html that shows each image with its prompt underneath and the exact model name the tool reported. 01. A high-fidelity iPhone screen for a roommate expense app called "Halves": a balance card that says "You're owed $128.40", a list of 4 recent expenses (Groceries $86.20 · Mina, Internet $60.00 · Jay, Pizza $36.00 · You, Electricity $112.75 · Sam) and a bottom tab bar with Home, Expenses, Settle, Profile. Aspect ratio 9:16. 02. A desktop dashboard for a small coffee roastery called "Ember Roasters": weekly revenue chart, top 5 beans with sales numbers, low-stock alerts, clean light theme. Aspect ratio 16:9.
