/* ============================================================================
   CREATIVE MODE — Apple-style "cover flow" career timeline
   Light studio UI: each career stage is a card; the active card sits in the
   center facing the viewer while the neighbours fan out in 3D.
   Scroll the wheel or drag the mouse like a touch swipe to move through
   the stages. Content of every stage lives on its card.
   Used together with creative markup in index.html + logic in cv-app.js
