Optional ReadonlyannotationOptional ReadonlyrenderersBuilt-in renderers that contribute semantic annotations to the
renderer-owned scene. When present, this list selects the enabled
built-in layers. Style-backed descriptors resolve into their established
presentation fields, while direct descriptors such as region retain
their semantic configuration for the backend. Existing style fields remain
supported for compatibility and source-specific presentation overrides.
