DeepSeek Palenight Theme

A theme for the dsh Harness Web UI, delivered in two forms:

1. Persistent dsh bundle (recommended) — package.json declares dsh.bundle.patch + dsh.client, so installing the package into a dsh profile makes the theme part of the host composition: it is served at /plugins/dsh-palenight-theme/client.js, listed in window.__DSH_BOOT__, and survives host restarts (same mechanism as @liustack/modlens).
2. Dynamic Cordis plugin — the original form (plugin/client.js + plugin/host.js), activated per-session via cordis_define/cordis_run; it dies with the process and is only kept for reference.

Both forms stack a token layer over the active theme — no rebuild of the harness shell is needed.

• Dark mode — Community Material Theme Palenight: indigo #292D3E surfaces, periwinkle text #A6ACCD, teal accent #80CBC4.
• Light mode — warm neutral: parchment #F5F4F0, warm grey text #4F4B45, teal accent #00897B.
• Code blocks get clear contrast in both modes.
• ~100 theme variables covered (surfaces, tabs/headers, inputs, menus, text tiers, borders, buttons, interactive states, code, scrollbars).

How it works

The dsh web frontend exposes a theme client service. overrideTokens(source, tokens) stacks a per-token CSS-variable layer on top of the active theme:

theme.overrideTokens('deepseek-palenight-theme', {
  '--dsw-alias-bg-base': { light: '#F5F4F0', dark: '#292D3E' },
  '--dsw-alias-brand-primary': { light: '#00897B', dark: '#80CBC4' },
  // ... ~100 tokens total
})

The browser half (plugin/client.js) applies the layer and registers small UI (run-card panel, composer status line). The host half (plugin/host.js) registers two package-private RPC handlers (demo/ping, demo/hello) and a model-visible demo tool (demo_greet) to prove both halves are live.

Activation (persistent bundle form — survives restarts)

The package is a dsh bundle: package.json declares dsh.bundle.patch (its cordis.patch.yml row) and dsh.client (the web client bundle). Install it so the dsh profile can resolve it:

1. Resolve the package from the profile. Either install it with pnpm in the profile directory (dsh plugin --profile web add dsh-palenight-theme, once published), or — for a local checkout — copy the package directory into the profile's dependency store and register it:
   • copy to ~/.dsh/profiles/node_modules/dsh-palenight-theme/
   • add "dsh-palenight-theme": "1.0.0" to dependencies in ~/.dsh/profiles/web/package.json
   • append dsh-palenight-theme to dsh.profile.bundles in the same file
2. Restart dsh. The row - id: dsh-palenight-theme composes into the host tree, and the client-modules registry adds /plugins/dsh-palenight-theme/client.js to the boot manifest (dsh.client.platform: web, immediately: true).
3. The theme applies at every boot. Switch dsh Appearance to Light/Dark/System — both palettes are themed.

To remove: drop the dependency and bundle entry, then restart.

Activation gate. The client bundle declares inject: ['theme'], so the plugin activates only after the theme service (provided by @deepseek-ai/dsh-client-ui-theme) is available. Do not remove it: with inject: [] the immediately: true bundle runs before ui-theme provides the service, ctx.get('theme') is undefined, and the token layer silently never applies.

Hot updates. dsh-client-hmr watches served bundle files, so replacing plugin/client-module.js (same package, new content hash) reaches the graph without a host restart.

Activation (dynamic form, deprecated — dies on restart)

1. cordis_define a new Plugin (kind: new, any idPrefix), pasting plugin/host.js as code.host and plugin/client.js as code.client.
2. cordis_run the returned pluginId/packageId (mode: run).
3. Approve the browser-side cordis/request-run prompt (client code only runs after you approve it).
4. The theme applies immediately. Switch dsh Appearance to Light/Dark/System — both palettes are themed.

To revert: cordis_stop <pluginId> restores the default theme and removes all effects (badge, cards, tools). cordis_undefine removes it permanently.

Notes

• Both halves are plain JavaScript (no TS/JSX/import). The client uses React.createElement only.
• Theme.listTokens exposes only 13 tokens; the frontend actually consumes ~100. overrideTokens accepts any token name (only the { light, dark } pair shape is validated), so the full set is overridable.
• Dark palette values are taken from the Community Material Theme Palenight VS Code extension (equinusocio.vsc-community-material-theme-1.4.7), whose license governs those colors; the code here is MIT.
