/* ================================================================
   COMPONENT: CUSTOM CURSOR — single-element architecture

   .cursor  →  position: fixed, positioned directly in root
               stacking context so mix-blend-mode: difference
               blends against the page (not a transparent parent).

   Position + visual state both live on the same element.
   JS writes the full transform string (translate + optional scale)
   so there is no CSS individual `scale` property — eliminating the
   compositing bug that caused a jump to (-200, -200) on click.
