dsh-dynamic-background

The default DeepSeek Harness chat surface is a single static color that offers little room for personal expression and can feel flat during long sessions. dsh-dynamic-background turns that surface into a gently rotating visual canvas: upload GIF, WebP, or APNG animations alongside any static image, or simply tap one of the twelve built-in solid-color swatches. All assets join a shared rotation queue that cross-fades every 3 to 120 seconds with a smooth opacity transition and an optional slow Ken Burns breathing zoom, so the backdrop keeps shifting without ever demanding attention.

Readability is handled automatically. Using stable data-* selectors, the plugin paints a translucent, theme-adaptive protective layer over the chat content column, the status bar, and the session header, keeping every word crisp no matter what is playing behind it. Background blur (0-12 px) and overlay opacity (0-90 %) let you tune the mood, while the settings panel exposes interval, transition duration, order versus random mode, and play/pause controls in a single glance. All images and preferences persist in the browser's IndexedDB, so they survive restarts and page refreshes without re-uploading; the plugin also honours the operating-system reduce-motion preference for users who prefer steadier visuals.

Everything runs entirely client-side with no backend, no build step, and no external services. Uploads use File.arrayBuffer plus pure-JS Base64, and the precompiled bundle installs instantly. It is a good fit for anyone who wants a subtle sense of motion in their daily DSH conversations without sacrificing text legibility or local data persistence.
