/**
 * A {@link MeshBatcher} variant that shades meshes with the active stage's
 * {@link Light3d} lights (half-Lambert diffuse from directional lights +
 * ambient). It extends the unlit batcher, adding a world-space `aNormal`
 * vertex attribute (12-float layout vs 9) and a lit shader.
 *
 * Meshes opt in via `mesh.lit` — so standalone, unlit meshes keep the lean
 * 9-float `MeshBatcher` and pay nothing for lighting. Both batchers share the
 * mesh-mode depth-clear state (a single clear per target) since this one
 * inherits {@link MeshBatcher#bind}.
