Android Crypto Portfolio Dark Tracker

A dark-mode Android crypto portfolio tracker app rendered at full-bleed on a Samsung Galaxy S24+ mockup. Background is near-black (#0A0A12) with a very subtle deep blue vignette. Top card: total portfolio value "$84,320.14" in 40sp white bold, with a 24-hour change badge "+4.2%" in a bright neon green pill. Below, a smooth area chart spans the full card width; the line is electric yellow with a gradient fill fading to transparent; data represents a 7-day price movement with one visible peak. Below the chart, a horizontal "Top Assets" list shows four rows: each row has a circular token logo placeholder (BTC in deep orange, ETH in silver-blue, SOL in purple-pink gradient, AVAX in red), ticker in 16sp white, token full name in 12sp muted gray, sparkline in 60px width, and price + percent in right-aligned text. Neon green for positive, coral red for negative. Bottom floating action button is a neon teal plus icon. Typography: Space Grotesk. Mood: sleek trader dashboard, restrained neon accents on dark ground.
