Theme Asuka // 02

简体中文

An unofficial fan-made Light/Dark appearance plugin for the DeepSeek Harness Web UI. It pairs restrained school blue, ribbon red, warm paper, and quiet Tokyo-3 night tones with three right-composed wallpapers that follow the local time of day.

Preview

Compatibility

• DSH: 0.2.0-rc.2
• Cordis: 4.0.4
• Node.js: >=20
• Target: Ubuntu / WSL2 Ubuntu with DSH Web and Linux Chrome

Version 3.2.2 targets DSH 0.2.0-rc.2. Its glass surfaces and high-opacity wallpaper behavior were checked in an isolated Windows DSH Web profile using the Codex in-app browser. On 2026-10-01, the user also confirmed normal state testing and real model streaming in WSL Ubuntu for the current version. See COMPATIBILITY.md for the current checks and limits.

Install

GitHub Release

Install the prebuilt 3.2.2 Release asset:

dsh plugin --profile web add https://github.com/Yyyyyylor/dsh-asuka-school-theme/releases/download/v3.2.2/dsh-asuka-school-theme-3.2.2.tgz

This project is not published to npm. The Release asset contains the prebuilt Host/Client code and all three public wallpapers. Restart the DSH Web profile after installing, updating or removing the plugin.

From a local checkout

In the repository root, run:

pnpm install
pnpm build
npm pack
dsh plugin --profile web add ./dsh-asuka-school-theme-3.2.2.tgz

The package filename should match the .tgz emitted by npm pack.

GitHub source tag

Install from the fixed v3.2.2 source tag:

dsh plugin --profile web add github:Yyyyyylor/dsh-asuka-school-theme#v3.2.2

This requires Git to be available on the host. Pin the tag instead of using main so updates remain predictable.

Use

• Open Settings → General → Theme-Asuka for the quick Off / On the Way to School / Noon Classroom / Tokyo-3 Night scene switch.
• Open Settings → Theme-Asuka for wallpaper period, opacity, blur, decorative details, reduced motion, and reset. In the default automatic setting, Early is 06:00–11:00, Noon is 11:00–17:00, and Night is 17:00–06:00; the wallpaper crossfades at each boundary.
• New-session and active-conversation composer cards share the same lighter, scene-aware liquid-glass surface, keeping more of the wallpaper visible.
• Assistant replies, reasoning, tool calls/output and errors share the message glass material and remain readable above 100% wallpaper opacity.
• Presented file cards and model submenus use matching rounded glass; file actions retain one shared frame and their native preview/menu behavior.
• The composer's add menu keeps its rounded frosted glass and blurs content behind it; clicking the workspace selector again closes its menu. Split dividers stop inside the rounded edges.
• The left sidebar, conversation header and docked right panes float above the wallpaper with matching rounded glass surfaces and visible gaps. The icon rail, pane resizing and narrow-window fullscreen behavior remain native; title-edit actions wrap when the center column runs out of room.
• Splitting the right sidebar smoothly expands a second pane; closing a split smoothly expands the surviving pane. Desktop fullscreen entry and exit smoothly change its width. Dragging remains immediate, and plugin/system reduced-motion preferences disable transitions.
• Narrow guide panes hide shortcut hints to keep entry names visible and restore them when widened. Selected dock tabs pair their fill and labels with the scene. Code banners use distinct scene fills and a fine divider to separate the title, code body and transcript.
• Use the edit action beside a conversation title to rename the current session without leaving the conversation view.

The default mode is Off. This plugin leaves the official Light, Dark, and System appearance unchanged; it only adds the selected wallpaper scene.

Wallpaper images are decoded before the existing crossfade starts, and likely next scenes are preloaded while the browser is idle. Range-control previews are frame-coalesced, so opacity and blur adjustments remain responsive without reapplying unrelated theme tokens. Previously decoded preset images are reused until plugin disposal; blur is applied to each wallpaper layer before its opacity crossfade, avoiding a filtered parent that flattens both changing layers. Palette variables are prepared off-document and applied in one style update.

Privacy and assets

No credentials, telemetry, image upload, or browser localStorage preference store is used. Scalar preferences are stored in DSH's plugin-owned Host entry's live Config form (asuka-school-theme). DSH migrates the old settings document into the profile; the entry ID and preference fields are unchanged. The three bundled WebPs are generated project assets; see assets/LICENSE.md and docs/ASSETS.md.

Do not package private artwork from assets/private/.

The Host reads only the three package-owned images and serves fixed GET/HEAD routes on the existing DSH Web server. The browser uses same-origin DSH transport for images, settings and explicit session-title edits. No third-party service, data upload, telemetry, credentials or subprocess is used. The runtime dependency is pinned Schemastery 3.18.4; DSH/Cordis are host-provided optional peers, not additional runtime installations. There are no installation lifecycle scripts. See Store review for dependency, permission and failure boundaries. Independent supply-chain review and Store automatic rechecking remain pending; declarations do not guarantee approval.

Development

Maintainers should start with the project index and the repository-specific agent guide.

pnpm build
pnpm test
pnpm check
npm pack --dry-run

The package publishes prebuilt lib/index.js and lib/client.js; end users do not need a postinstall build. See docs/RESEARCH.md for the historical implementation notes and docs/COMPATIBILITY.md for remaining live integration checks.
