+# OpenAI Shadcn — Hermes Desktop theme
+
+A complete `@hermes/plugin-sdk` Desktop theme with a neutral light/dark palette
+and an optional floating-panel treatment for the built-in layout tree.
+
+![Dark preview](./assets/preview-dark.png)
+
+## Demonstrates
+
+- `THEMES_AREA` with full light and dark `DesktopTheme` palettes
+- `requestTheme()` for an imperative, persisted activation
+- `PALETTE_AREA` commands for activate and one-click rollback
+- `ctx.storage` for user intent across plugin reloads
+- Theme-gated CSS that disappears immediately when another theme is selected
+- Stable `data-slot` / `data-tree-*` hooks for scoped Desktop polish
+
+The CSS does not replace the pane tree. Sessions, profile/gateway routing,
+resizing, collapsing, dragging, Files, Terminal, and Review remain core-owned.
+
+## Install from this examples repository
+
+```bash
+mkdir -p ~/.hermes/desktop-plugins
+cp -R openai-shadcn-desktop ~/.hermes/desktop-plugins/openai-shadcn
+```
+
+Hermes Desktop hot-loads the folder. If needed, run **Reload desktop plugins**
+from `Cmd/Ctrl+K`.
+
+The theme activates on first load. Palette commands:
+
+- **Theme: activate OpenAI Shadcn**
+- **Theme: return to Hermes default**
+
+## Standalone distribution
+
+The independently versioned package, release ZIPs, and update instructions live
+at https://github.com/agentik-os/hermes-openai-shadcn.
+
+## Notes
+
+The plugin is intentionally production-shaped rather than a minimal one-method
+snippet: the full palette and the floating layout are the behavior being shown.
+All custom layout rules are gated by
+`data-hermes-theme="openai-shadcn"`, so rollback is immediate and complete.
