A warm parchment theme for DeepSeek Harness.
The name reads as "A-div": the backslash and the division sign are the same
stroke drawn two ways.
Paper-toned canvas, burnt-orange accent, ring-based depth, and a serif/sans
typographic split — implemented as a client-half DSH plugin.
What it does
Redefines the DSH client's semantic colour tokens (--dsw-alias-*) plus the
type stacks on body, so every surface, border, label, button, and state colour
in the interface follows the palette. It also sets the serif voice on content
headings and on the blank-session hero headline, and rewrites the turn-status
label.
Installing the bundle is enabling it. There is no settings row and no
toggle: mounting the row in the profile is the switch, and disabled: true in
cordis.patch.yml is how you turn it off again.
Install
From GitHub:
dsh plugin --profile <name> add github:Age10-Moyu/dsh-adiv-theme
From a tarball, if you downloaded a .tgz release:
dsh plugin --profile <name> add ./dsh-adiv-theme-1.0.0.tgz
dsh plugin forwards to pnpm inside the profile directory, then reconciles
dsh.profile.bundles against what actually installed — so the bundle joins the
layer stack automatically and you do not edit the list by hand.
Then restart the profile: dsh.profile.bundles is read once at start.
To disable it again without uninstalling, add to the profile's
cordis.patch.yml:
- id: dsh-adiv-theme
disabled: true
The patch layer is hot-reloaded on long-lived surfaces, so toggling it this way
should not need a restart. Changing the bundle list does.
To remove it entirely:
dsh plugin --profile <name> remove dsh-adiv-theme

Every neutral in the ramp carries a yellow-brown undertone; there are no cool
blue-greys in the light or dark palette.
Design decisions worth knowing
Coral, not burnt orange, in dark mode. #c96442 on #141413 does not reach
a comfortable contrast ratio, so the dark palette uses the lighter coral.
Warm dark surfaces are deliberately restrained. A strongly brown dark grey
reads as a dirty yellow smear on many real displays. The dark steps here move
toward neutral as they get darker, keeping the warmth perceptible without the
cast.
Ring shadows, not drop shadows. --dsw-shadow-lv1/2 are rebuilt as
0 0 0 1px rings with a whisper-soft offset.
No fonts are bundled. The stacks name the branded serif first, so an
installation that legitimately has it uses it, then fall back to Georgia and the
platform UI/monospace faces.
Typography anchors on semantic elements first, and on a stable class suffix
where no such element exists. The host's own classes are CSS-Modules hashes
regenerated on every build, so message headings are matched as h1–h6. The
blank-session hero headline is not a heading element — the host renders it as a
bare <span> — so it is matched through the _headline suffix that CSS-Modules
preserves. The hash prefix changes per build; the suffix does not. UI chrome
keeps the sans stack.
Tolerating host drift
Three host implementation details are relied on, and none of them is a
published contract:
- the
--dsw-alias-* / --dsw-static-* token names;
- the
_headline and _turnStatus CSS-Modules class suffixes;
- the two source strings of the turn-status label.
If DeepSeek Harness changes any of them, the theme degrades rather than breaks:
- tokens renamed → the affected surface falls back to the host colour. The
rest of the palette still applies.
_headline renamed → the hero headline returns to the sans stack. Nothing
else is affected._turnStatus renamed, or the label reworded → the status text is left
exactly as the host ships it. The shimmer colour still follows the palette.
The text pass has no blind-substring fallback on purpose: a global replacement
would mangle unrelated content — paths, escape sequences, and code.
Every pass is wrapped so a failure in the copy rewrite cannot stop the
stylesheet from being applied. Colours are the point of the theme; the copy is a
garnish.
Scope and limitations
- This plugin styles the web client only. It has no host-side behaviour.
- Surfaces that belong to a marketing landing page — hand-drawn illustrations,
alternating full-bleed light/dark chapters, oversized hero typography — have no
counterpart in an agent chat interface and are intentionally not imitated.
- A design system is not a layout engine. This theme changes colour, type, and
depth; it does not restructure the interface.
- The theme rewrites one label in the live DOM. That is the only place it reaches
beyond styling.
