rs_server_catalog/stac_api.md
Shared stac-fastapi-pgstac API instance.
Since stac-fastapi-pgstac 6.4.0, the library no longer exposes module-level
app/api/settings globals (see instantiate_api in
https://github.com/stac-utils/stac-fastapi-pgstac/releases/tag/6.4.0). This module builds
them once so they can be shared between rs_server_catalog.app and
rs_server_catalog.middleware.catalog_middleware without a circular import.
