Moneta

Build "Moneta", an investing tracker. The home screen shows the total portfolio value in large type above a line chart the user can scrub with a finger: while scrubbing, the value and the date above the chart follow the finger, with a light haptic tick on each data point. Under the chart, range buttons 1D, 1W, 1M, 1Y and ALL animate the line smoothly from one range to the next; the line and the change label are green when the period is up and red when it is down. Below that, a Holdings list and a Watchlist (for example AAPL, MSFT, NVDA, AMZN, TSLA) with a small sparkline and a colored change pill on each row. Tapping a stock opens a detail page with a candlestick chart, key stats (open, high, low, volume, market cap) and the user's position, with a Buy button pinned at the bottom. Buying goes through an amount keypad, an order review and a slide-to-confirm control, and ends with a confetti burst. Use realistic seeded sample data so the app opens straight into the portfolio, with no sign-in, onboarding or empty state. Make it feel premium: rich color, depth, spring animations, haptics and clean typography.
