/**
* The `settings` object used in the sidebar app that is a result of merging
* (filtered and validated) configuration from the host page with configuration
* from h / the browser extension.
* `SidebarSettings` are created by merging "sidebar configuration"
* (`ConfigFromSidebar`) with "host configuration" (either
* `ConfigFromAnnotator` OR `ConfigFromEmbedder`).
*
* In all cases, the annotator ("host frame") provides `ConfigFromAnnotator`
* to the sidebar frame by encoding values into a URL fragment on the sidebar
* frame's `src` attribute.
*
* In most cases, `SidebarSettings` combine `ConfigFromAnnotator` with
* `ConfigFromSidebar`:
*
* +--------------------------------------------+
* | host frame (annotator) |
* | +-----------------------+ |
* | | sidebar frame | |
* | | | |
* | <ConfigFromAnnotator> => iframe.src | |
* | | | |
* | | | |
* | | | |
* | | <ConfigFromSidebar> | |
* | +-----------------------+ |
* +--------------------------------------------+
*
* In some cases (e.g. LMS), host configuration should instead be provided by an
* ancestor ("embedder") frame. This is signaled by the presence of a valid
* `requestConfigFromFrame` object on `ConfigFromAnnotator`.
*
* `ConfigFromEmbedder` will then be requested from the designated embedder
* frame and combined with `ConfigFromSidebar` to produce `SidebarSettings`:
*
* +------------------------------------------------------------------------+
* | embedder frame |
* | +------------------------------------------+ |
* | | host frame (annotator) | |
* | | +---------------------+ | |
* | | | sidebar frame | | |
* | | | | | |
* | | <ConfigFromAnnotator> => iframe.src | | |
* | | requestConfigFromFrame | | |

* @typedef {Omit<ConfigFromHost, "reportActivity">} ConfigFromAnnotator
