   Pawdforward Studio — the 3D storefront
   A fixed WebGL stage; HTML acts scroll over it and drive one camera timeline.
   Palette, spacing and type inherit the main site's tokens (css/pf.css).
   Mobile first: every act is designed at 375px, desktop is the adaptation.
   Every act is fully readable with WebGL off, JS off, or reduced motion on.
