dsh-nico-theme
English | 中文 · Changelog
A switchable liquid-glass theme for the DeepSeek Harness web UI. Header, sidebar, composer, docks, and conversation pads become frosted panes over a living fluid backdrop (image or video wallpaper is optional). Turning the plugin off restores the stock UI — no DSH source changes.
Panels leaning together with the pointer under hover elasticity
Hover elasticity, recorded at maximum strength (0.5); the default is 0.2.
Contents
What it is
A DSH client plugin. The panel glass is rendered by nico-glass-kit: every pane portals a GlassSurface, whose backdrop runs an SVG displacement filter, so the glass bends the picture along its rounded corners instead of only blurring it. The fluid backdrop, wallpaper layers and reading pads are this repo's own CSS/canvas work. Not affiliated with DeepSeek.
Highlights
- Mica floating glass panels (32px main-panel corners, 18px popup corners, nico-glass-kit material), or compat mode (stock layout, frosted material)
- Panes cover the header, sidebar, composer, docks, dialogs, menus, model lists, background-task popover and new-session capsule, including multiple transient panels of the same kind
- Popups start with configured frosting before refraction becomes ready; panes share the material settings, with a stronger neutral tint on the right sidebar for file previews. Selected rows, header tabs and small buttons use rounded outlines and subtle highlights
- Fluid backdrop with hue / depth knobs; optional image or video wallpaper with its own blur slider
- Material knobs on the kit scale: blur, brightness, refraction, depth, curvature, dispersion, rim highlight
- Hover elasticity: the glass, icons and panel content lean together using the shared setting; the settings window stays stationary, and
prefers-reduced-motion turns motion off
- Reading pads for user bubbles, assistant prose, reply actions and the trajectory
- No adaptive text color

Origins
This repository is a fork of WYH66666666/DSH-Transparent-UI-Plugin (MIT, © 2026 John Wu), adapted for DSH 0.2.0-rc.2 / 0.2.1-rc.2.
The panel glass — refraction, bevel, tint, rim light, and elasticity — is rendered by nico-glass-kit (0.3.4, MIT). The fluid backdrop, wallpaper layers, and reading pads are this repository's own CSS/canvas work.
Requirements
@deepseek-ai/dsh@0.2.1-rc.2 (tested version)- Node.js 22+
- The refraction pass wants a Chromium browser; Firefox and Safari fall back to the kit's plain CSS frost on their own
Install
DSH plugins live on a profile, not in the global dsh install. dsh plugin add runs pnpm inside that profile and, because this package declares dsh.bundle, appends it to dsh.profile.bundles automatically. Then restart the profile.
Daily Web UI
dsh plugin --profile web add dsh-nico-theme@latest
Then restart dsh web. Enable Nico glass theme in Settings → Built-in Plugins → Nico Theme. Every knob lives on the dedicated Nico Theme page in the settings left nav.
Throwaway profile (does not touch web)
# Run only when creating this profile for the first time.
dsh --profile nico-theme-test --from-default-profile web --dump-config
dsh plugin --profile nico-theme-test add dsh-nico-theme@latest
dsh --profile nico-theme-test --host 127.0.0.1 --port 18765 --no-open
Update later with the same command (@latest) or dsh plugin --profile web update. Remove with dsh plugin --profile web remove dsh-nico-theme.
From a local checkout (development)
pnpm install && pnpm bundle
# Run once to create the test profile; skip if a web test profile already exists.
dsh --profile nico-theme-test --from-default-profile web --dump-config
dsh plugin --profile nico-theme-test add .
dsh --profile nico-theme-test --host 127.0.0.1 --port 18765 --no-open
Develop
pnpm install
pnpm bundle # tsdown + lib/types/*.d.ts
pnpm typecheck # tsc --noEmit against the installed DSH client packages
pnpm visual # Playwright checks against the test profile
pnpm readme-shots # refresh dark-mode images (set NICO_WALLPAPER; optional NICO_THEME_DEMO_TITLE selects one named local demo session)
pnpm readme-gifs # record assets/*.gif (needs NICO_THEME_URL; settings clip also needs NICO_WALLPAPER)
The material itself lives in nico-glass-kit; this repo mounts it onto DSH's panels and wires the knobs to its settings page.
Maintainers: npm login, then git tag v0.1.0 && git push origin v0.1.0. GitHub Actions publishes the tarball (needs repo secret NPM_TOKEN). Or pnpm publish locally after pnpm bundle.
