Optimize Parqet Portfolio View in a At-a-Glance Mode.

Portfolio Dashboard as a Progressive Web App (PWA). Connects via Parqet Connect API (OAuth2 PKCE) to display all portfolios in a single overview with key metrics: market value, cost basis, net performance, return %, TTWROR, daily change, and net dividends. Daily changes are calculated using previous close data from Yahoo Finance (via yfinance). Each portfolio is expandable with a sortable holdings table. Dark and light mode. Designed for mobile use — installable as Android/iOS app. Auto-refreshes every 5 minutes. This is a private, non-commercial project — no investment advice, no guarantee of availability.
