Arknights-flavor-theme: Arknights-Themed Skin for DeepSeek Harness

The DeepSeek Harness (DSH) plugin “Arknights Visual Style” uses CSS variables and DOM injection to provide a Rhodes Island-inspired UI customization for DSH, including a cyan HUD, particle effects, light sweeps, and atomic model icons. The plugin does not depend on other functional plugins and only modifies styles. Installation requires Node.js and pnpm, and one-click deployment via the provided script is recommended. Note that similar theme plugins may override each other, and style injection is not supported on DSH shell pages. Theme assets are embedded as base64, and after upgrading DSH, selectors should be updated as needed when existing styles stop taking effect.
