-FinWise — FastAPI backend for HuggingFace Spaces
--------------------------------------------------
-• Serves all static HTML/CSS/JS files from the same directory
-• /api/quotes?symbols=NVDA,AAPL,MSFT   → live quotes via yfinance
-• /api/chart?symbol=NVDA&days=8        → daily closes for sparkline
-• Full CORS enabled so the browser JS can call these endpoints freely
-• Runs on port 7860 (HuggingFace default)
