Create a vertical 4:5 (1080x1350) mixed-style visual showing a 5-level tiered commission ladder for Tapsite's Indonesian affiliate program, with each level glowing progressively brighter. Background: Diagonal split gradient — upper-left half in clean off-white #FAFAFA, lower-right half in subtle cool navy #0F172A at 15% opacity, creating a soft atmospheric depth. A subtle spotlight beam shines from top-center downward, illuminating the ladder. Visual metaphor — Ascending Arch/Stairway: A vertical staircase of 5 floating platforms, each one higher and slightly larger, arranged in a gentle curve from bottom-center to upper-right. Each platform is a translucent glass shelf with subtle blue-white glow underneath. Level 1 (bottom, subtle glow): 'Level 1 - TapMaster Starter' #475569, badge '30% recurring', seed icon. Level 2: 'TapMaster Active' #1E1B4B, badge '35% recurring', plant icon. Level 3 (center, bright glow): 'TapMaster Pro' #1E1B4B, badge '40% recurring', tree icon. Level 4: 'Creator Partner' #0F172A, badge '45% recurring', star badge icon. Level 5 (top, brightest with golden accent): 'Growth Partner' #0F172A, badge '50% recurring' in gold/amber, crown/trophy icon. Connecting: Thin upward-pointing arrows in bright blue #2563EB between platforms, small sparkle particles near top. CTA (bottom-center): 'Mulai dari 30%. Naik sampai 50%.' in #1E1B4B bold, underline accent in #2563EB. Style: Premium SaaS gamification aesthetic, clean geometric platforms, subtle glassmorphism, no people. Mood: Aspirational, progressive, achievement-oriented.
