DeepSeek Harness Plugin: Angelina Light and Dark Glass Themes

The DeepSeek Harness plugin `bilbillm/deepseek-harness-angelina-themes`, maintained by bilbillm, is a theme plugin designed to preserve the native interaction layout while replacing only the visual layer. It is licensed under MIT and offers Angelina light and dark glass themes, featuring a frosted glass effect and restrained background parallax, with unified visual styling for elements such as menus and cards. The plugin includes intelligent performance optimization, automatically disabling parallax on low-performance devices, narrow screens (viewport width ≤ 900px), touch interactions, or when the system's reduced motion setting is enabled. Users can install it via the `dsh plugin` command from GitHub or a local directory, requiring Node.js 20+ and DeepSeek Harness Web.
