dsh-theme-newsprint

A DSH theme plugin. It carries the newspaper typography of Typora's newsprint theme into the DSH Web GUI. Pure CSS, no hooks, no image assets.

• Light — warm paper #f5f3ed, ink text #1f0909, a single sea-blue accent #065588; the neutrals are one eight-step warm paper ramp, below.
• Dark — a warm dark newsprint: stock #1a1815 (warm brown-black, neither #000 nor blue-black), warm-white ink #ece7dd, accent lifted to #5aa9d6. The newsprint character is kept rather than deferred to the stock neutral black.
• Body — the whole document switches to a serif stack: Georgia → PT Serif → Noto Serif SC → SimSun.

Palette

Both schemes share one role vocabulary (paper.* is the surface ramp from most raised to hardest rule, ink.* the text ramp from strongest to most decorative); the colours live in SCHEMES in lib/client.js, so retuning one value moves the whole app. The token map is built by buildTokens(scheme), so each scheme generates its own set from the same role names.

Ink ramp, with contrast against base: primary #1f0909 17.2:1, secondary #5a5049 7.1:1, dimmed primary #6b6156 5.5:1, tertiary #776c62 4.6:1, caption #948a7e 3.0:1 (metadata only), decorative #c3bbae.

The single accent is the sea blue #065588 (7.1:1), reserved for links, focus and the info state; the brand colour and the primary button are ink, deepening to #3f2d22 on hover; green, amber and red are all desaturated to a printing-ink register.

Two hard rules: every neutral must be a step of the warm paper ramp above — a true neutral grey (r=g=b) reads as dirt on warm paper; and every translucent colour is derived from its opaque source by alpha(), never a hand-written rgba.

Install

This plugin is standalone: it depends on no market, skin center, or third-party store. It is an ordinary profile bundle, installed with dsh plugin alone.

# from the repository
dsh plugin --profile web add github:2754LM/dsh-theme-newsprint

# or the prebuilt tarball (no full-repo download)
dsh plugin --profile web add https://github.com/2754LM/dsh-theme-newsprint/releases/latest/download/dsh-theme-newsprint.tgz

Refresh the page afterwards; if the theme does not appear, restart dsh once (the bundle list is read at startup).

Enable / disable / uninstall

• Disable / re-enable: edit ~/.dsh/profiles/web/cordis.patch.yml

  - id: newsprint
    disabled: true    # true to disable; false or delete the row to enable
  

  The loader hot-reloads. With the plugin installed but not enabled, dsh looks exactly like the stock theme — no typography leaks.

• Uninstall:

  dsh plugin --profile web remove dsh-theme-newsprint
  

Multiple themes: two enabled themes stack on each other. Keep exactly one enabled and write disabled: true for the rest.

What it brings

The character of a newspaper layout is not in its colours but in its strokes. So besides the light palette swap, the body typography is rebuilt the way a newspaper sets type:

The serif font reaches the body via two paths so neither depends on an undocumented dsh internals line:

1. font-family: var(--dsw-font-family) on body (chrome picks it up);
2. explicit font-family on [data-dsh-part='message-body'] and [data-chat-anchor-key'] (markdown picks it up), so a future dsh refactor of var(--dsw-font-markdown-base-font-family) cannot silently drop the serif.

Anchor selectors are stable attributes, not hashed class names. .markdown is a CSS-Modules class that compiles to a hash (._markdown_kcgor_5 in the current build), so a literal .markdown selector matches nothing, and [class*=...] would break on every rebuild. [data-chat-anchor-key], [data-dsh-part="message-body"], .md-code-block, and [data-code-block-banner] are all stable.

Form

A cordis instrumented plugin: package.json declares dsh.bundle.patch (its own cordis.patch.yml, which inserts the loader entry id: newsprint) and dsh.client (platform web). It does not depend on @deepseek-ai/dsh-client-ui-theme, does not call ctx.theme.register(), and has no runtime dependency on any market or skin center.

The host half's apply() is a no-op; the client half does one thing: append a single <style id="dsh-theme-newsprint-styles"> element to <head> with the light tokens + L3 typography, and add a dsh-newsprint-active class on html to scope it. The fiber-dispose hook removes the class and the <style>.

The benefit is durability against dsh client-topology refactors. When dsh-client-runtime was split into the two dsh-api-* controllers in 0.1.5-rc.2, every plugin that went through ctx.theme broke (services collided at fiber time). This plugin only injects CSS into the DOM, so it is immune. The cost is that no "light/dark" picker of the theme runtime can drive it, so the scheme is decided in CSS instead: dsh writes data-ds-dark-theme on <body> (boot-theme.ts in ui-theme), and this plugin branches on that attribute without subscribing to any theme service. That is also why the two schemes must handle specificity carefully — the dark block and the light block carry the same specificity by default, so they are separated with :not() and an explicit attribute selector.
