react-native-maps

native-seam over a real host-thread maplibre-gl driver (render-worker/map-host.ts), NOT an OSM iframe. the package JS (MapView/Marker/Callout/AnimatedRegion/createFabricMap) runs unchanged; only the RNMapsMapView/RNMapsMarker host components + the RNMapsAirModule TurboModule are ours. maplibre renders keyless OpenFreeMap vector tiles at device scale on the host and ships each frame to the shell painter via the live-frame channel. Childless Markers render as real maplibre circle layers; custom Marker child views render in the tenant overlay and reproject from host camera feedback. Pinch (focal-point zoom) + pan are forwarded from the tenant responder, and maplibre camera changes return through the host→tenant channel for region callbacks and current imperative reads. The imperative ref API works: getCamera/getMapBoundaries/getPointForCoordinate/getCoordinateForPoint answer from web-mercator math over the seam's tracked camera; animateCamera/animateToRegion/setCamera/fitToCoordinates/fitToElements route through codegenNativeCommands → __dispatchCommandImpl → the maplibre easeTo/jumpTo/fitBounds host commands. takeSnapshot captures and encodes the visible map viewport through the compositor pixel owner, including png/jpg, quality, base64/blob-uri results, and requested output dimensions.
