Liquid Glass for DeepSeek Harness

A layered liquid-glass skin for the DSH web UI. Sidebar, conversation column, right rail, pages, composer, conversation header and settings menus are re-materialised as glass; the page background becomes a wallpaper that rotates with the time of day; a small sun button in the bottom-right corner opens the control panel.

Every glass surface is generated by one contract (displacement map → blur → contrast → brightness → saturation → rim), so any layer at any setting is the same material as the sample capsule.

What you get

• 13 adjustable glass regions — sidebar, conversation column, right rail, in-column pages, home hero, composer, question card, conversation header, selection highlight, new-session rows, composer controls, dialogs & menus, and the draggable sample capsule.
• 14 knobs per region — tint, tint saturation, concentration, blur, contrast, brightness, saturation, rim strength, displacement scale, chromatic aberration and friends. Every knob actually moves something; there are no dead sliders.
• Time-of-day wallpapers — three bundled images rotate by clock (04:00–11:59 / 12:00–17:59 / 18:00–03:59), re-checked every 30 s. Four more bundled images ship as ordinary wallpapers: pick one to pin it, delete it, or upload your own. Uploads and deletes are written to disk.
• Four theme colours — official DeepSeek blue (default), gold, white, black. Applied to the host colour ramp and to the new-session layer.
• Selection highlight — the active sidebar row or settings nav cell carries glass; switching sends a lens flying from the old position to the new one (spring, stretch, trail).
• Scheme-aware concentration — tint concentration and brightness follow the light/dark scheme on the seven large surfaces, so a light scheme does not get a heavy wash.
• Bundled font — HarmonyOS Sans SC (three weights) is served from the package and published as --dsw-font-family; nothing is installed system-wide and uninstalling removes it.

Install

dsh plugin add @istarry/dsh-ui-liquid-glass

Then restart the DSH service (fully quit the desktop app, or restart dsh web).

Use

Click the sun button in the bottom-right corner:

• 主题 / Theme — wallpapers, theme colour, text colour.
• 控件 / Controls — one tab per region, 14 knobs each, plus a shared sample capsule.

Every value persists automatically. There is a reset per page and a full reset.

Permissions and behaviour

Read this before installing — the plugin is not a passive stylesheet:

• Writes to disk. It creates ~/.dsh/ui-liquid-glass/wallpapers on first activation and seeds it with the bundled wallpapers, adding only files that are missing (never overwriting yours). The Default/ subfolder is kept in sync with the bundled rotation set and is pruned; the root of that folder is yours and is never pruned.
• Serves HTTP routes on the host web server: GET /ui-liquid-glass/wallpapers (list), GET /ui-liquid-glass/wallpapers/<name> (bytes), POST / DELETE on the same path (add / remove), and GET /ui-liquid-glass/fonts/<file> for the bundled font. Hosts without a web server never resolve these routes; the picker then hides upload/delete.
• Overrides host CSS tokens. It publishes --lg-* variables, remaps a number of official --dsw-* tokens (backgrounds, menu surfaces, hover fills) and sets --dsw-font-family. Everything is scoped under body[data-lg-skin], so removing the plugin restores the official look.
• Stores preferences in localStorage under ui-liquid-glass/skin/v4 (browser side only).

Compatibility

• Tested against DSH 0.2.0-rc.2.
• Peer dependency: @deepseek-ai/cordis ^4.0.1.
• The client half is a self-contained bundle and declares no dsh.client.inject; it hooks only official CSS tokens, official layout local names, and ARIA roles.

Bundled assets and licences

• HarmonyOS Sans SC — Copyright 2021 Huawei Device Co., Ltd. Redistributed unmodified under the HarmonyOS Sans Fonts License Agreement, which permits bundling with software. The full licence is at assets/fonts/LICENSE_Fonts.txt. The font files must not be modified or redistributed standalone.
• Wallpapers — bundled for demonstration. If you repackage or redistribute this plugin, replace them with images you have the rights to.

Building from source

The repository ships prebuilt lib/ output, so installing from the repository never runs a build. To rebuild locally you need a DSH source checkout — tsconfig.json extends the host's tsconfig.base.client.json and tsdown.config.ts imports the host's client preset:

pnpm install
pnpm exec tsc -b .
pnpm exec tsdown

The package name in tsdown.config.ts is written into the emitted bundle (window.__ModuleLoader__.load({ id })) — renaming the package means editing that file and rebuilding.
