 This configures how clustering behaves. Clustering ensures the map page can render assets smoothly even with 40-50 thousand assets. The clustering option can be disabled, or changed to cluster markers in a smaller radius showing more clusters and changed to start clustering at a certain zoom level. Note that reducing cluster radius or cluster max zoom can have performance impacts. The recommended cluster max zoom level is Maximum realm zoom level - 2.

-**Map - Preset filters:**
+#### Preset Filters Configuration
+
 This configures map preset filters, which add a dropdown on the map page to quickly filter the visible assets by type, attribute values, realm, and more using an `AssetQuery`. A live matching-asset count badge is shown per filter option. Options without a `label` will have an auto-derived label based on the type names and attribute values. Selected filters are persisted across page reloads (per user and realm) and reset on each new login session. You can also specify an optional `default` boolean or an array of `realms` to limit where the filter applies. Note that unsupported query fields like `orderBy`, `limit`, and `offset` will result in a warning.
