dsh-md3-theme

The DSH Web GUI is clean out of the box, but if you crave the pill-shaped buttons, systematic color steps, and soft state overlays of Material Design 3, the native theme may feel just a step short. dsh-md3-theme was made to close that gap. Instead of hand-picking hex values, it calls Google's official HCT color engine (@material/material-color-utilities, the same algorithm behind Material Theme Builder) and derives a complete Vibrant-variant MD3 palette from the DeepSeek Blue seed (#4176e6). Every role—primary, surface steps, outline, error, and the 8%/12%/14% state-overlay percentages—is scientifically computed, in both light and dark schemes.

Under the hood the plugin stays deliberately minimal. A pure host-side add-on hooks into the webServer.tapIndex seam and injects a block of high-specificity CSS into every index.html response, overwriting --dsw-alias-, --dsw-specific-, shadows, font stacks, focus rings, and selection highlights in one pass. No bundler, no client-side runtime, no third-party dependencies. Uninstall it and the interface snaps back to stock DeepSeek, as calm as the water after a whale swims by. Buttons become Extended-FABs, list items grow pill-shaped radii, hover and pressed states follow the MD3 overlay formula—all Material flavor, zero changes to the native codebase.

The plugin suits two kinds of users best: pixel-perfect regulars who want every button, sidebar panel, input, and send key to share one harmonious color language; and tinkerers who enjoy recoloring—ship with any seed or variant by re-running the included scripts/generate-palette.mjs, and the entire palette regenerates in one shot, every component updating automatically. Change the hue, watch the whale change color: that simple.
