dsh-thumb: Mobile Adaptation Shell for the DSH Web Interface

dsh-thumb is a mobile layout adaptation plugin for DeepSeek Harness (DSH). By transforming the sidebar into an overlay drawer and adjusting the settings page into a full-screen single-column layout, it addresses the issues of an overly narrow reading area and incompletely displayed controls on mobile devices. The plugin can be flexibly enabled or disabled, does not affect the desktop version, and uses semantic positioning to minimize version compatibility issues. Note that it is written for a specific version, and the author has declared the release to be final, with no further maintenance.
