大漠落日 · 归雁南飞 — @zhangwenlei1404/dsh-theme-desert-dusk

A theme plugin for the DeepSeek Harness Web GUI, built on the poem 「大漠孤烟直，长河落日圆」.

It paints a full-viewport desert-at-dusk scene behind the app and tints the UI with a matching warm palette.

What it draws

A single inline SVG (no external image files, no network requests):

• a dusk sky gradient, from violet through cinnabar to pale gold
• a round sun setting behind the far ridge, with a soft glow
• the long river crossing the dunes, carrying the sun's reflection
• four layers of dunes, darkening toward the foreground
• four flocks of geese flying south in V formation, fading and shrinking with distance
• a star field that twinkles gently, disabled under prefers-reduced-motion

What it changes in the UI

• 18 --dsw-alias-* design tokens are overridden through ctx.theme.overrideTokens, in light and dark pairs: base and raised surfaces, borders, text labels, brand accent, and the four semantic states
• the shell's top-level containers are made transparent so the scene reads through them, with a contrast scrim between the art and the UI to keep text legible

Install

dsh plugin --profile web add @zhangwenlei1404/dsh-theme-desert-dusk

Or straight from this repository, without npm:

dsh plugin --profile web add github:zhangwenlei1404/dsh-theme-desert-dusk

After installing, hard-refresh the page (Ctrl+Shift+R / Cmd+Shift+R).

Replace web with your own profile name if yours differs (@zhangwenlei1404/dsh-theme-desert-dusk is a bundle, so it has to be enabled in the profile that serves your client).

Uninstall

Disable it in Settings → Plugins, or remove it with:

dsh plugin --profile web remove @zhangwenlei1404/dsh-theme-desert-dusk

Notes

• The scene is drawn entirely in CSS and inline SVG data URIs, so it still works offline.
• The palette overrides are !important, so they win over the active theme's own tokens while the plugin is enabled.
• No Host service, no background process, no network access.
