ds-whale-send-button

When you use the DeepSeek Harness Web chat interface day to day, the send button is just a generic arrow icon with no brand character. ds-whale-send-button fixes that small visual gap by swapping the primary send-button icon with the official DeepSeek whale graphic, giving the UI a sense of brand consistency without altering any behavior.

Under the hood, the plugin uses a CSS mask to overlay the official whale path (sourced from dsh's own favicon.svg) onto the button. The color is set to currentColor so it automatically follows the button text color in both light and dark themes. The targeting logic is precise—anchored to the send arrow's SVG path prefix—so it never touches the stop button, queue button, or any neighboring icons. It is a pure browser-side style override with zero dependencies and no injected JavaScript.

This plugin is ideal for DeepSeek Harness users who care about visual consistency and brand polish. If you simply want the button you stare at every day to become a little whale, this plugin is light enough to install, take effect immediately, and remove whenever you like.
