/* ─────────────────────────────────────────
   Kingwinston template — stylesheet

   Architecture:
   - Tabs nav is persistent (one DOM element,
     never cloned). Its active slot grows
     instantly when .stage[data-active] changes.
   - Content area is what gets cloned. During
     navigation, two .content elements coexist
     briefly. GSAP animates them.
   - The moving tab(s) get a FLIP transform
     applied at the same time so they appear
     to slide together with the content.

   No CSS transitions on layout properties.
   All motion handled by JS via GSAP.
