dafy-whale-theme: A blue plump whale theme plugin for the DeepSeek Harness web frontend

`dafy-whale-theme` is a community theme plugin for the DeepSeek Harness (DSH) web frontend, maintained by DViridescent and licensed under MIT. This plugin transforms the `dsh web` interface into a "blue whale" visual style, featuring core functionalities such as ocean blue light/dark dual themes, dynamic bubbles and fish schools, "Daily Fish Sayings" above the input box, an interactive DeepSeek girl mascot in the bottom right corner, and brand icon replacement in the top left corner. It also supports narrow sidebar adaptation. Installation requires pnpm and can be completed via the official CLI with the command `dsh plugin --profile web add github:DViridescent/dafy-whale-theme`. After installation, the service needs to be restarted.
