dsh-neu-theme

A Neumorphism (soft-UI) theme plugin for DeepSeek Harness web — gentle raised-and-recessed surfaces in a cream light palette and an ink-dark palette, complete with ambient lighting, material gloss, grain texture, glassmorphism and micro-interactions.

中文说明见 README.zh.md。

Features

• Two themes registered into the built-in ThemeRuntime:
  • neu-light — cream warm-white canvas, soft slate-blue accent
  • neu-dark — ink-blue night canvas, luminous indigo accent
• Lighting — ambient top glow + corner fill painted on the visible surfaces (conversation canvas, sidebar, details column), not just body.
• Material — three-layer shadows (contact + cast + top-edge highlight), 145° gloss gradients aligned to the light direction, code blocks with a backlit inner wall.
• Texture — fine grayscale grain (inline SVG feTurbulence) over the canvas, sidebar, details column and code blocks.
• Glassmorphism — the composer capsule and its popovers (permission menu, model menu, context panel) share one frosted-glass language: the card's blur lives on a ::before pseudo-layer so the nested popovers keep their own real backdrop-filter blur (the card is not their backdrop root).
• Micro-interactions — conversation nodes fade in on mount, bubbles lift on hover, the composer recess deepens on hover/focus, tool rows and reasoning rows strengthen on hover; all gated under @media (prefers-reduced-motion: no-preference).
• Settings row — Settings → General gains a Neumorphism picker (Default / Neu Light / Neu Dark), persisted through the Host settings document.
• Default is pristine — selecting Default (or having no saved skin) leaves the document exactly as dsh ships it: no injected stylesheet, no body attribute, native colors and shadows.

Install

Install the published package into a dsh profile (works with the web profile):

dsh plugin --profile web add dsh-neu-theme
# or install manually in the web profile:
cd ~/.dsh/profiles/web
pnpm add dsh-neu-theme

The package is also available on npm.

Then add "dsh-neu-theme" to dsh.profile.bundles in the profile's package.json, and restart dsh web.

Once running: Settings → General → Neumorphism theme → pick Default / Neu Light / Neu Dark. The choice is stored in the Host settings namespace dsh-neu-theme (normally ~/.dsh/settings.yaml); choose Default to return to the built-in appearance.

The Host-backed settings path requires DSH Web Host 0.1.1-rc.2 or newer. Remote browsers cannot access the loopback settings API, so their selection remains process-local by design.

Develop

npm run build   # regenerates lib/client.js from src/client.tpl.js + themes/*.json
npm run check   # syntax-checks the built bundles

While dsh web runs with the HMR chain mounted, rebuilding lib/client.js is picked up by the polling watcher and hot-reloads only this plugin's fiber.
