Create a vertical 4:5 (1080x1350) mixed-style visual for a social media post about landing page conversion tips. Background: Warm-to-cool diagonal gradient from #FAFAFA at top-left transitioning to subtle #E2E8F0 at bottom-right. Soft radial glow at center, hint of #2563EB glow coming from bottom edge. Visual metaphor — Three floating glassmorphism cards cascading diagonally from top-left to bottom-right. Card 1 (top-left): shows a messy page layout with question marks, text "Jual apa?" in muted gray, semi-transparent. Card 2 (center): clean landing page preview with bold headline, one blue CTA button, checkmark icon, text "Buat apa gue butuh?". Card 3 (bottom-right): rocket icon and Rupiah symbols, text "Kenapa harus percaya?" with sparkle effect. Faint connection lines between cards. Small checklist element at bottom-left with 3 checked items. Clean editorial illustration style with glassmorphism elements. No stock photos. Mood: professional, educational.
