DeepSeek Harness Message Rendering Plugin: dsh-tavern-renderer

The DeepSeek Harness plugin dsh-tavern-renderer focuses on message presentation and does not modify persistent data or model prompts. It provides a complete rendering pipeline that supports ordered regular expression substitution, macro variables, secure inline JavaScript expressions, Markdown parsing, and strict HTML/CSS sanitization. The plugin includes eight immersive document templates and supports custom themes and character templates. Installation requires compatibility with DSH 0.1.7-rc.2; after installing via the command line, users can configure regular expression rules, invoke built-in or custom variables, and switch themes or inject styles through the API. The plugin runs entirely in the browser and has no backend dependencies.
