/* ==========================================================================
   Kisaka stage — stacked full-viewport scenes driven purely by position:sticky.
   Every scene sticks at top:0 inside one tall container, so each new scene
   slides over the frozen one before it. Nothing scrolls "down"; scenes replace
   each other in place. JS (js/kisaka-stage.js) only reads progress and syncs
   the rail, pagination and hash — it never drives the movement.
