/* ============================================================
   Page transitions
   Single brand-colored curtain that reads as one box passing:
   - Exit: the curtain (with logo) rises from the bottom and covers
     the old page, then the browser navigates.
   - Entry: the new page first paints still covered by the same-colored
     preloader, which continues the motion by wiping off the top.
   Overrides the theme's dark #preloader in style.css.
