Detailed Description

Builds the per-frame Visibility result (every scene mesh, and which of them the camera sees).

Runs after the Transform stage, whose world transforms it culls. Views through FrameContext::hostView when offered, else the active camera; culls every Mesh in parallel (frustum -> distance -> screen size) and publishes on FrameContext::visibility. Every drawable mesh is also gathered, seen or not, so off-screen occluders and offline captures survive frustum culling.
