/**
|
|
* Fails when a built chunk contains both WebGL map engines.
|
|
*
|
|
* mapbox-gl and maplibre-gl used to be static imports in the same three
|
|
* components, so rollup emitted a single 2.8 MB chunk carrying both. Every map
|
|
* user downloaded 1.8 MB of mapbox plus 1.1 MB of maplibre and ran one of them.
|
|
* A stray static import anywhere in the map tree brings that straight back, and
|
|
* nothing else would notice — the build stays green and the app still works.
|
|
*
|
|
* The markers are chosen to appear only inside the SDKs themselves, verified in
|
|
* node_modules. Do NOT test for the bare string "maplibre": the provider value
|
|
* 'maplibre-gl' and the setting key maplibre_style also appear in app code, so it
|
|
* matches the shared core chunk too.
