dsh-mobile-css: DSH Web UI Mobile Adaptation Plugin

dsh-mobile-css is a mobile adaptation plugin specifically developed for the DeepSeek Harness (DSH) Web UI. Through pure CSS injection and two lightweight auxiliary scripts, this plugin optimizes the user experience on mobile devices or narrow-screen windows, featuring zero dependencies, no source code modification, and the ability to be uninstalled at any time. Core features include establishing a compact typography system, ensuring touch targets for controls are at least 44px, preventing Android input focus auto-zoom, implementing a drawer-style sidebar interaction, and optimizing full-screen browsing on the settings page. Furthermore, it includes specific optimizations for the input area layout, message bubble display, fixed-format statistic rows, and Markdown table wrapping. The plugin is activated when `pointer: coarse` or a viewport width is less than or equal to 1024px, ensuring the desktop experience remains unaffected. Users can install it via the DSH Web UI.
