balance-dock: A Persistent Balance Viewer Plugin for DeepSeek Harness

balance-dock is a resident web plugin for DeepSeek Harness (dsh), designed to display account balances in real time. It solves the issue of balance data being lost on refresh, with core features including always-on persistence, secure data retrieval (using same-origin endpoints only), automatic refresh, theme adaptation, and multi-currency support. Installation requires configuring an API key, and installing via the dsh command is recommended. By leveraging its persistent mechanism, the plugin delivers a seamless and secure balance-viewing experience.
