 Installed bundles and their plugin rows display their own title and description in the current UI language on cards and detail pages. Each field falls back from exported locale `meta` to the accessible `package.json` at that plugin address; the final title is the full package or module name, with no package description when both sources omit it. See [Plugin display metadata](../../../docs/cookbook/adding-a-package.md#plugin-display-metadata) for the author format. Bundle cards, details, and component rows display the image declared by their own `package.json.icon`; absent or undecodable images retain the default artwork. Installation previews still use registry or manifest information.

 Custom item pages use the Host entry id as their registration id; row pages use the bundle package and row id. The page owner supplies `form.state` and `form.mutate(operations, expectedRevision)` when the entry exposes editable Config fields.

 `plugins.bundle.config` supplies bundle detail configuration, keyed by npm package name. `plugins.bundle.activation` offers bundle-owned guidance after explicit enablement from the list, with callbacks to dismiss it or open the bundle details. It does not appear merely because an enabled bundle was listed.
