dsh-pixel-ui: DeepSeek Harness Pixel Skin Plugin

dsh-pixel-ui is an appearance plugin maintained by zhang66633 within the DSH ecosystem, designed to reskin the Web GUI into a pixel RPG style. It adheres to the "everything is a plugin" philosophy and does not introduce new core features. The plugin offers four themes: "Pixel·Cottage," "Pixel·Parchment," "Pixel·Warm Sun," and "Pixel·Terminal Green," and supports one-click switching back to the modern default UI. Visually, it employs the fusion-pixel and Press Start 2P fonts, featuring retro effects such as stepped hard shadows, 8-bit buttons, and CRT scanlines. User preferences are stored via browser localStorage, with "pixel-wood" as the default theme. To install, execute `dsh plugin add dsh-pixel-ui` in the dsh terminal.
