SceneStaticLayerCache class
Cache for the static scene layer (background + grid).
Why: avoid re-drawing the grid every frame when inputs are unchanged.
Invariant: the cache key must match size, background, grid, camera offset,
and grid stroke width.
Validate: test/render/scene_static_layer_cache_test.dart.
