dsh-matrix-theme

The dsh web GUI ships a solid dark-base palette, but the look is unmistakably utilitarian. dsh-matrix-theme swaps in a Matrix-inspired green-on-black theme with a faithful port of the zengrz.github.io glyph wall as an ambient backdrop: glyphs cascade from the top of the screen, a cursor spotlight tracks your pointer, and the whole frame carries a subtle 3D tilt, turning a terminal tool into an immersive code-rain canvas.

Under General settings you get a Matrix theme toggle and, right below it, a Rain effects row with three levels. Full is the complete reference effect with full-density glyph wall, per-glyph churn, cursor spotlight, and 3D tilt all enabled. Lite halves the glyph draw density, drops churn and spotlight, and culls near-invisible columns for integrated-GPU or older machines while keeping the 3D tilt and marching white cell. Off disables the canvas entirely; the green palette stays and the rain costs nothing. Switching levels rebuilds the engine at the new density instantly, and the preference persists via localStorage. At boot the plugin detects whether the harness declares a shell.backdrop slot: if so the rain mounts in the frame backdrop layer, otherwise it falls back to a fixed-position DOM canvas behind the app root driving the same RainEngine, and the fallback retires itself if the slot appears later. The published entry points are committed, so no build step runs at install time.

The theme is purely decorative, marked aria-hidden, and nothing reaches a model request. It is aimed at everyday developers who want a visual dressup for their dsh session without any model-side cost.
