Theme: Clean APP operation popup showcase board for 618 limited promotion.
Subject: 618 limited promotion defines the campaign topic. Four popup cards show flash sale alert, member-only discount, countdown reward, and bundle upgrade offer as production-quality mobile UI concepts.
Composition: Vertical 9:16 pure-white design proposal board with a top title and a precise 2x2 grid of four rounded popup cards; generous spacing, consistent hierarchy, and clear component alignment.
Signature elements: Each popup varies its icon element, information structure, benefit angle, and button treatment while staying in one coherent design system. Feature points include limited-time price, countdown timer, gift badge, and one-tap claim button.
Style: Polished app-design presentation with rounded cards, soft shadows, subtle glow edges, vivid but clean colors, tactile buttons, and small supportive 3D UI elements.
Color palette: Bright campaign colors balanced with white space and accessible contrast.
Typography: Use the readable title 618 CAMPAIGN POPUP SYSTEM; popup microcopy can be short, clean, and UI-like.
Restrictions: Keep the transformed subject coherent, preserve the intended composition, maintain crisp visual detail, use clean readable text when present, and keep the background focused and uncluttered.
