深度求索时，派一只像素蓝鲸为你喷水摆尾。

A DSH (DeepSeek Harness) web UI plugin: while the model is thinking, the native 「深度求索中…」/ "Deep diving…" status row becomes a pixel-art DeepSeek blue whale spouting and wagging its tail, next to the same status text rendered in a pixel font with a glyph-level shimmer.

Features

• 🐋 Animated pixel whale — the hand-drawn DeepSeek blue-whale art (40×25 grid, 6-tone palette), expanded into an 84-frame spout + tail-wag loop, downsampled to 27×18 and painted as a CSS sprite sheet (steps() animation).
• 🔤 Real pixel font — Fusion Pixel 12px, subsetted to exactly the characters the status row uses (ASCII + the Chinese glyphs + a narrowed middle dot), embedded as WOFF2 so it works offline.
• ✨ Glyph-level shimmer — the moving highlight is clipped to the text glyphs (background-clip: text), so it travels across the strokes instead of the row.
• 📐 Sits on the text baseline — align-items: baseline on the status row puts the bottom of the whale on the same line as the bottom of the glyphs, hugging the text on its left.
• 🎯 Non-invasive — the native text node, language, timer and update logic are untouched; only CSS is applied to the thinking row.
• 🪶 Zero runtime overhead — no MutationObserver, no polling, no timers, no DOM writes after setup. The client half injects a single <style> element and nothing else runs, so there is no per-frame work and no memory growth while streaming.

Install

From the DSH plugin market, or:

dsh plugin --profile desktop add https://github.com/Lkrain821/dsh-pixelwhale

Then restart DSH.

How it works

• The host half (lib/index.js) is a client-only cosmetics entry — it just mounts the bundle and exposes the browser half via exports["./client"].
• The client half (lib/client.js) injects one <style> element containing:
  • @font-face rules for the subsetted pixel font, scoped with unicode-range;
  • a sprite-sheet background-image + @keyframes on the native whale icon ([data-chat-running="true"] [class*="runningIcon"]), which replaces the shipped whale drawing without inserting any node;
  • background-clip: text shimmer and the pixel font on the status text;
  • align-items: baseline on runningContent so the whale bottom lines up with the text baseline;
  • a prefers-reduced-motion: reduce fallback that pins the first frame and drops the shimmer.

Everything is keyed on the [data-chat-running="true"] attribute DSH puts on the thinking row, so the whole effect appears and disappears with that row.

Verified against DSH 2.0.20-next. Selectors are attribute/substring based (data-chat-running, runningIcon, runningContent, runningText) rather than hashed CSS-module names, so they tolerate ordinary client rebuilds.
