/* =========================================================
   GAJANAN CINEMATIX — FOOTER TO NEXT-PAGE TRANSITION
   Additive only. Does not change existing page layout.

   The transition layer is a FIXED full-viewport overlay that is
   completely hidden (display:none) until JS triggers the reveal.
   It is never in the document flow, so it adds no page height
   and can never be scrolled into view.
   All animations use transform + opacity only (no filter/blur).
