   Hero · 360 viewer + cursor-mask reveal
   Base = final render, slowly panning.
   Reveal = a stack of stages (wireframe → massing → materials → warm → cool).
            Only one stage is "on". The whole layer is masked to a circle
            around the cursor — so the user sees the other-version of the
            space wherever they hover.
