# cyber-particle — Particle Network Background Plugin for DeepSeek Harness

English | [中文](./README.md)

Adds an animated particle-network background to the DeepSeek Harness web UI: gray particles drift in from random screen edges, cross the viewport in straight lines, and re-enter from a new edge after leaving; particles closer than a threshold distance are automatically connected with lines, forming a continuously evolving mesh.

Rendered in a full-screen overlay with `pointer-events: none`, it never intercepts clicks or scrolling and does not change any UI colors. No npm runtime dependencies.

All logic lives in the browser half: no server-side behavior, no `webServer` route. Settings persist in browser `localStorage` (key `cyber-particle:config`) and restore automatically after a page refresh or restart; dshmarket can toggle the plugin like a skin (no route conflicts).
