/* ============================================================================
   site-fx.css — visual/interaction chrome for the motion + mobile-native
   layers (grain, bottom sheets, swipe-snap, drawer, thumb nav).
   Loaded only on marketing pages, alongside site-motion.js / mobile-native.js.
   Everything is inert until the JS adds the corresponding element/class, so it
   is safe even if the scripts fail. All heavy motion respects reduced-motion.
