Introducing the Sunny Cherry Blossom and Night Cherry Blossom Theme Plugins for DeepSeek Harness

`dsh-sakura-theme` is a community-maintained DeepSeek Harness plugin that provides “Sunny Sakura” light and “Night Sakura” dark themes by rewriting visual tokens at a low level. It automatically follows system preferences, redefines branding, typography, and interactions, includes the built-in LXGW WenKai font to enhance the Chinese reading experience, and features dynamic petal effects. Installation requires running the `dsh plugin add` command via the CLI, and after installation the `dsh web` process must be fully restarted. The plugin disables the official brand placeholders for visual consistency and requires a DeepSeek Harness 0.1.1-rc.2 and Node.js 20+ environment.
