+## Theme and layout
+
+Plugin UI runs on desktop, browser, iOS, and Android, across every Paseo theme. `theme` is a typed `PluginTheme`. Color and spacing must come from those props. Unstyled `Text` is black and fails in dark themes.
+
+Recreate styles when `theme` or `layout.compact` changes.

+| `theme.colors.surface0`        | Root view                  | Panel background                    |

+| `layout.platform`              | Platform-specific behavior | `ios`, `android`, or `web`          |
+
+Do not hardcode `#000`, `#fff`, or React Native's default text color. Primary copy uses `foreground`. Labels use `foregroundMuted`. Tighten padding when `layout.compact` is true.
+
+Workspace and agent panels receive the same `theme` and `layout` fields.
