- ranker: dedicated POI_GATES/POI_QUALITY for landmarks & lairs — they were
routed through BUILDING_GATES (roof_visible/single_building/no_front_facade),
so volcanoes, ley-confluence formations and lair camps failed every gate and
burned generations to the regen cap.
- grok_generator: _ensure_grok_sdk re-checks the import per candidate path and
raises a clear 'set GROK_BUILD_SDK_PATH' error instead of a cryptic ImportError.
- grok_generator: submit_batch generates a sprite's variants concurrently via
asyncio.gather so the client's max_concurrent semaphore is actually used.
- add test_grok_pipeline.py — 49 headless checks (factory, POI-gate routing
regression, prompt adaptation, PNG validation, starter manifest).
