dsh-ui-font: DeepSeek Harness Web GUI Plugin

The dsh-ui-font plugin resolves the issue in the DeepSeek Harness Web GUI where font families cannot be changed. After installation and restarting the `dsh web` process, users can customize body and code fonts in the settings. The plugin uses browser permissions to read local fonts and supports building font stacks. The configuration is stored in CSS format and includes fonts such as JetBrains Mono by default. The plugin overrides existing styles with `!important` rules and sanitizes stored content to ensure security.

dsh-ui-font: Client-side plugin for adjusting DSH interface font

## Introduction DSH's philosophy is "everything is a plugin," but the client interface's text display—body font, code font, scaling, and line height—lacks a built-in setting to adjust them. In Chinese environments, encountering font fallbacks often means you have to manually modify styles. dsh-ui-font turns this into a plugin: after installation, it allows for centralized adjustment of the entire interface's text display in Settings → Fonts. Changes are previewed in real-time, and settings are stored in browser localStorage, remaining persistent after a refresh. Below, I will introduce its features, installation methods, and precautions. ## What is this? dsh-ui-font is a DSH client plugin maintained by linshufan21 and open-sourced under the MIT license. In one sentence: it modifies the entire DSH interface.

dsh-ui-font: Customizing Fonts and Font Sizes for the DSH Web Interface

dsh-ui-font is a community plugin designed specifically for the DeepSeek Harness (DSH) web interface, aimed at resolving font style and font size adjustment issues. The plugin supports independent selection of regular text and code fonts from system-installed fonts, and provides a global font size adjustment slider ranging from -3 to +20 pixels. Its core feature includes a "crosshair selection" mode, which allows users to precisely locate and individually adjust font sizes in specific areas via mouse interaction, along with a fine-tuning list per interface plugin region. The plugin supports three customizable shortcut slots (UI capture, zoom in, zoom out) for quick operations. Setting data is persisted to the DSH server-side settings.yaml, and it is compatible with a localStorage fallback mechanism for offline or older version scenarios. Technically, it is developed based on React and does not bundle fonts.
