dsh-raiden-theme: DeepSeek Harness Inazuma Raiden Workshop Theme

`dsh-raiden-theme` (Raiden Inazuma Atelier) is a theme plugin focused on the visual style of the DeepSeek Harness Web interface, developed by lengzhanbao. It features dual-mode wallpapers (light sakura / dark thunderstorm), purple-gold acrylic dialog boxes, and chibi-style icons. It includes ambient particle effects and workspace animated images, and supports reduced motion and opacity adjustment. It also provides a standalone “Raiden Shogun” Agent preset. The plugin changes the appearance by injecting CSS without affecting core logic, and is compatible only with the DSH Web profile.
