The shadow map frustum is fitted to the camera view every frame. The visible area is projected into the light's coordinate system to compute the tightest possible bounding box, so no shadow map texels are wasted on off-screen geometry. Zoomed out, shadows cover the whole map at lower resolution. Zoom in, and the shadow map tightens to give you crisp, detailed shadows on individual tiles. This prevents blocky shadow artifacts when you zoom in.
