dsh-yoimiya-theme

The default DeepSeek Harness UI is cool and utilitarian. dsh-yoimiya-theme replaces the entire visual layer with the atmosphere of Yoimiya from Genshin Impact: the dark palette evokes a summer festival night with warm orange fireworks bursting against the dark, while the light palette feels like washi paper under soft daylight. The two modes are independently designed rather than a simple inversion, using warm indigo-black with warm rice-white and a warm-toned syntax highlight. Contrast ratios are measured and exceed WCAG AA, so extended reading is gentler on the eyes than pure black-on-white.

On the interaction side, a firework button in the corner spawns live particle animations: a fuse with a trailing spark rises, bursts on schedule, and embers fall under simulated gravity before fading out. Rise speed, density, and burst size each offer three levels, and everything pauses the moment you switch windows so nothing lingers in the background. A built-in local music player treats a folder on your machine as the library: drag audio files in, and you can play, seek, adjust volume (remembered across sessions), and even crop square covers. All files stay local; the theme makes zero network requests. The wallpaper also reacts to context, fading from full brightness on the homepage into a subtle backdrop the moment you start a conversation.

Nearly every visual element is drawn in code, so the package stays tiny and recoloring is just tweaking numbers. The theme is well suited for DeepSeek Harness users (Web or Desktop) who want a distinctive, character-driven look, appreciate the Genshin Impact character Yoimiya, and still value accessibility and lightweight performance. The theme never uploads files, and uninstalling leaves your music folder untouched.
