A pixel-perfect Android stock portfolio tracker screen in dark mode, Material Design 3 visual language. The top shows the portfolio value "$73,245.88" in 32px bold white and today's change "+$1,204.12 (+1.67%)" in bright green. Below is a large interactive-looking area chart spanning the full width, showing a 1-month upward-trending portfolio line in green-to-teal gradient fill, with the area below the line filled in a very dark teal. The time selector tabs (1D, 1W, 1M, 3M, 1Y, ALL) are shown with 1M active in a filled teal chip. Below the chart, a stock holdings list shows 4 rows: "NVDA" (green +3.1%), "AAPL" (red −0.8%), "MSFT" (green +1.2%), "AMZN" (green +2.0%) — each row has the ticker symbol, a tiny sparkline, current price, and day change. A floating action button (teal, "+ Add") sits above the Material bottom nav bar.
