DeepSeek Harness Font Plugin: Independent Typography Control for Conversations, Interfaces, and Code

`dsh-fonttune` is a font enhancement plugin for DeepSeek Harness (DSH), designed to address the limitations of a single default typography style. The plugin separates typographic control for conversation, interface, and code areas independently, offering fine-grained adjustments to font family, font size, line height, font weight, and ligatures. It supports real-time parameter tuning through a floating panel, font size offset, relative font weight adjustment, and three text rendering styles. In addition, the plugin supports preset scheme management, independent fallback lists, and font stack editing in advanced mode, enabling efficient and flexible visual customization.
