Retro Macintosh for DeepSeek Harness

Work like it's 1997. · 像 1997 年那样工作。

English | 中文

A classic Mac OS 8/9 Platinum skin for the DeepSeek Harness Web GUI — a trip back to 1997: platinum greys, Chicago/Geneva/Monaco type, pinstripe wallpaper, beveled controls and hard shadows.

⭐ If you enjoy it, give the repo a star — it helps more people discover the plugin.

Why you'll love it

• Nostalgia, done right — a faithful System 7 → Mac OS 9 design language, not just a grey theme: platinum chrome, classic fonts, pinstripe desktop, beveled buttons, hard shadows.
• Completely self-contained — the Chicago web font is inlined as base64 and the pinstripe is pure CSS. The whole plugin is one 47KB file, zero external assets, zero downloads.
• Four themes in one — Platinum (light) and Graphite (dark), each with Classic Blue or System Teal highlights, an homage to the Appearance Manager's customizable accent palette.
• Immersive — all 103 design tokens the web shell consumes are remapped; no modern DeepSeek blue-grey leaks through.
• Respects your defaults — switching back to the built-in appearance restores it pixel-identical, no injected styles remain.

Features

• Two skins, four themes — Platinum (light) / Graphite (dark) × Classic Blue / System Teal.
• Full token coverage — every one of the 103 design tokens is remapped; verified at build time.
• Chicago web font, zero external assets — the free ChicagoFLF clone is inlined as a base64 @font-face; Geneva and Monaco come from the OS with graceful fallbacks.
• Pinstripe desktop — the iconic System 7 / Mac OS 8 wallpaper in pure CSS, no image downloads, no licensing issues.
• Beveled Platinum controls — buttons with the classic 2px inset highlight/shadow bevel, double-rule default buttons, sunken inputs, square scrollbars with black arrow glyphs, hard 2px 2px 0 drop shadows, near-zero border radius.
• Barber-pole progress — indeterminate progress indicators render as the classic striped marquee.
• Happy Mac easter egg — an optional startup splash (inlined SVG, off by default) with a toggle in the settings row.
• Your choice is remembered — skin, accent and splash persist per browser in localStorage.
• Zero intrusion on Default — switch back anytime; pixel-identical restore.
• Accessible — respects prefers-reduced-motion; micro-interactions disabled on request.

Requirements

• DeepSeek Harness web profile (dsh web / dsh --profile web)
• Any modern browser (ES modules + CSS custom properties)

Installation

# from your harness checkout (the npm exec wrapper that boots `dsh`)
dsh plugin --profile web add dsh-retro-mac

Or add it by hand in the profile's package.json:

{
  "dependencies": {
    "dsh-retro-mac": "^0.1.0"
  }
}

Then restart the web profile and refresh the page. A Retro Mac settings row appears with:

• Skin: System (built-in), Platinum, Graphite
• Accent: Classic Blue, System Teal
• Splash: Happy Mac startup screen toggle

Development

# rebuild lib/client.js from src + themes (zero-dependency, plain Node)
npm run build

# syntax-check the generated bundles
npm run check

The build validates that every generated theme covers the full 103-key baseline and inlines the Chicago font, so a stale or partial theme fails loudly.
