DeepSeek Harness Codex Theme Appearance Plugin

`dsh-codex-theme` is an appearance plugin designed specifically for DeepSeek Harness (DSH), intended to meet specific aesthetic needs through theme customization. It maps Codex theme configurations to the DSH token system and provides 80 presets (26 light and 54 dark). Core features include switching between light and dark mode within the panel, customizing fonts and font sizes, instant preview, and settings persistence. Installation requires a Node.js ≥ 20 environment and can be completed by adding it via a CLI command. Note that font detection is system-dependent, and the plugin can be disabled or uninstalled at any time. It provides DSH with a rich and consistent set of configurable visual styles.
