Portada de app de compras

Create a high-fidelity, fully realistic mobile e-commerce app homepage screenshot for the store, market or product niche described in the user request, with complete commercial UI logic and strong visual polish. Build the layout top to bottom: a status bar showing 9:41 with signal and battery icons; a search header with a location selector on the left, a rounded search field carrying a relevant placeholder query, and message and scan icons on the right; a row of horizontal category tabs; a large promotional carousel banner announcing a seasonal sale with bold discount copy; a grid of ten small labeled function icons; a flash-sale module with a live countdown timer and three product cards showing slashed prices; a two-column recommended-for-you waterfall with at least six product cards including photos, titles, prices and sales tags; and a five-item bottom tab bar. Render every interface label crisply and consistently in the language implied by the user request, with realistic fonts, spacing, soft shadows, rounded corners, dividers and promotional tag treatments, so the whole frame reads as a genuine app screenshot rather than concept art. Use an invented store identity only — no real brand names or logos, and no watermark. User request: a Chinese grocery app with fresh produce deals, or a minimalist sneaker shop in English
