Create a vertical 4:5 (1080x1350) mixed-style visual for a WhatsApp blast about "AI website tips". A modern smartphone screen floating in center showing a before/after comparison — left side a blank boring website input "My business" and right side a vibrant detailed website input "I sell cookies, target moms 25-40, elegant pink theme". The phone screen emits a soft blue glow (#2563EB). Background: diagonal gradient from #0F172A (dark navy top-left) to #FAFAFA (near white bottom-right) with subtle light rays. Floating minimalist icons around: sparkle stars, a magic wand, and small geometric shapes in transparent glassmorphism style. No real people — use abstract silhouettes or icons only. Modern, clean, tech-forward aesthetic with depth through layering and soft shadows.
