dsh-sidebar-footer-stack: Vertical Stacking and Drag-and-Drop Reordering of Sidebar Footer Cards

DSH Sidebar Footer Stack is a plugin that resolves the issue of multiple cards being cramped in the DeepSeek Harness sidebar footer. It converts horizontally arranged cards into a vertical stack, unifies their appearance, supports drag-and-drop reordering, and persists the saved order. Built with pure JavaScript and supporting hot replacement, the plugin relies on host-specific structures and may break after updates.
