dsh-dracula

A third-party Dracula dark theme for the DeepSeek Harness web UI. Dark-only, covers the full --dsw-alias-* layer plus --shiki-* syntax highlighting, and ships a "Themes" settings page for switching.

Quick read (for agents)

• What it is: a DSH bundle npm package that registers a third-party theme (dracula) through the client theme service ctx.theme.register(...), recolouring the whole web UI by overriding --dsw-alias-* and --shiki-* CSS tokens.
• Shape: one package is both the bundle and the client plugin — package.json declares dsh.bundle.patch (→ cordis.patch.yml) and dsh.client (→ ./client).
• Files: src/client.tsx (theme registration + settings page + persistence), src/index.ts (empty host half), cordis.patch.yml (one self-referential row dsh-dracula).
• Persistence: localStorage key dsh.dracula-theme.preference mirrors every theme/change; restores on startup, defaults to dracula on first run. Guarded against quota/privacy/parse failures.
• Build: pnpm install && pnpm build (tsdown → lib/client.js, lib/index.js).
• Install on another DSH: dsh plugin --profile web add dsh-dracula.
