DeepSeek Tactical CRT Theme

@dsh-external/dsh-crt-theme is a browser-only DSH skin that turns DSH Web into a readable instrument terminal. It includes a black/red/orange/amber Unit-02 display and a black-violet/acid-green/magenta Unit-01 display, with condensed labels, flat cut-corner controls, fine diagonal progress tracks, dense vertical context meters, a restrained scanline layer, aperture grille, and glass-edge vignette.

The visual direction is an original 1990s industrial sci-fi terminal treatment. It does not ship or redraw DeepSeek, Evangelion, or other third-party brand assets, logos, or interface text.

Install

GitHub

Install the published build directly into a DSH Web profile:

dsh plugin --profile web add github:WJNCT55555/dsh-crt-theme
dsh web

The repository keeps lib/ under version control, so this path does not require a local TypeScript toolchain.

Local checkout

cd dsh-crt-theme
dsh plugin --profile web add .
dsh web

The bundle inserts the dsh-crt-theme loader row. If the profile already contains the row, remove the duplicate before enabling the bundle.

The skin installs a caller-owned DSH theme token layer when it loads. Unloading the plugin restores the normal DSH palette preference, and the Settings panel can release the same layer without unloading the plugin.

Installing from a local checkout with link: keeps the profile pointing at this directory, so a rebuild takes effect without reinstalling:

pnpm install
pnpm run build

Visual system

• Unit-02 is the tactical palette: black surfaces, red structure, orange controls, warm amber signal ink, and teal success states.
• Unit-01 is the synchronization palette: black-violet surfaces, magenta structure, acid-green signal ink, and orange alerts.
• Both schemes preserve each DSH control's native chrome: borderless text and icon actions stay borderless, while component-owned outlines receive the CRT palette.
• Orbitron is preferred when it is already installed locally; the skin falls back to bundled system fonts and does not fetch remote font files.
• The skin leaves compact icon buttons to their owning DSH components, so fixed-size toolbars retain their original geometry.
• Page-view tabs remain transparent labels; their selected state uses a short left indicator and an underline instead of a button container.
• Task and completion tracks use a thin diagonal CRT fill; the context breakdown keeps its semantic colors in dense 3 px vertical cells.
• The conversation composer keeps DSH's transparent editing layer and shared text metrics so backdrop-rendered draft text stays visible and aligned with the native caret.
• A blank conversation opens with DEEPSEEK、袭来 and a scan-striped DeepSeek whale mark; the sidebar carries the same mark.
• Brand text and session rows remain unframed navigation text, using only hover fill and a short selected-state indicator.
• The existing DSH shell stays intact: the skin adds no tactical status bar or decorative header above the product chrome.
• The achievements gallery keeps its own content layout while inheriting the condensed type, hard edges, buttons, and fine CRT meters.

Controls

Settings panel

The skin contributes its own section to DSH Settings (the section is labeled CRT 主题). It carries two independent switches and the palette picker:

• 启用 CRT 配色 — releases or reinstalls the skin's theme token layer. Turning it off restores DSH's own palette immediately; the panel stays in place, so the switch is always reachable.
• 硬件特效 — turns the scanline, grille, vignette, and phosphor-flicker layer on or off without touching the palette.
• 配色方案 — picks between the Unit-02 and Unit-01 palettes, previewed by a color swatch on each card.

Every change applies immediately and is persisted; the panel and the shortcuts below write to the same preferences, so they never disagree.

Shortcuts and API

• Ctrl+Shift+Alt+C on Windows/Linux, or Cmd+Shift+Alt+C on macOS: toggle scanlines, vignette, grille, and phosphor flicker.
• Ctrl+Shift+Alt+P on Windows/Linux, or Cmd+Shift+Alt+P on macOS: switch between Unit-02 and Unit-01 CRT palettes.
• window.DSHCRT.enable(), .disable(), .toggle(), .setScheme('unit02' | 'unit01'), and .toggleScheme() are available for local development. The former amber and violet inputs remain accepted as aliases.
• Preferences are stored under dsh-crt-theme:enabled, dsh-crt-theme:effects, and dsh-crt-theme:scheme.

The effect layer respects prefers-reduced-motion and removes all global state when the plugin is unloaded.

Compatibility

• Requires the DSH Web client token, slots, conversation, sidebar, and theme packages available in DSH 0.1.0-rc.8 or newer.
• It can be installed with dsh-achievements and dsh-web-preview-float. It owns one theme-token layer and styles their controls only visually; it adds no routes, tools, persistence, or host services.
• Do not enable a second full-page theme plugin at the same time: the later token layer and CSS rules win where they overlap.
