dsh-gemini-m3e-theme

DeepSeek Harness ships with a utilitarian Web UI by default. If you are drawn to the luminous Material 3 Expressive aesthetic that Google Gemini uses—soft dual-tone tokens, the Google Sans type stack, pill-shaped controls, a radial hero glow—there was previously no clean way to apply that look without patching source files. dsh-gemini-m3e-theme packages the entire visual layer into a persistent client bundle plugin that works exclusively through the official theme-token override channel and the style-injection channel, leaving zero product code untouched.

It covers six dimensions in depth: color (71 light-and-dark dual-tone tokens aligned to the Gemini luminous palette, with borders defined by surface contrast rather than stroke lines), typography (Google Sans Text fallback stack, a Mono variant for code, M3E heading scale at weight 400 with 1.5 line-height), shape (a precise radius system—40 px composer, 999 px pills, 32 px dialogs, 16 px tool blocks), glow and motion (a radial luminous hero glow, all transitions driven by a single cubic-bezier(.05,.7,.1,1) emphasized curve governing pop-in, staggered float, and dialog entry), interaction (pixel-accurate click ripples on pills and menus, interpolate-size width and height transitions, scrollbar edge fade-out and fade-in), and shadow (one soft-shadow spec shared by menus, popovers, and the Composer overlay, light on white and layered on dark, with border rings removed). Remove the bundle and every injected style disappears with it, restoring the original look with no residue.

It suits users who want a Gemini-aligned visual language inside Harness without maintaining a separate CSS patch, and teams that prefer M3E motion curves and pill geometry for a consistent brand feel. The repo ships a pre-built client bundle, so there is no local build step required—install, restart, and the theme is live.
