/* ---------- morphing sticky header ----------
   --navp (0 → 1) is set on .nav from scroll progress by lobby.js, and the
   dark full-width bar becomes the floating white pill in lockstep with the
   scroll — no on/off switch point.

   PERFORMANCE: nothing here re-lays-out the header's contents. The earlier
   version interpolated max-width + padding on .nav__inner (and max-width on
   the links and Dashboard), which forced a full flex re-layout of every
   button and text run on every single frame — that was the judder.

   Now the split is:
     · .nav::before  — a single childless plate is the only box that
                       resizes; laying out one out-of-flow element is O(1)
     · brand/actions — ride translateX/translateY (GPU-composited)
     · links/Dashboard — fade only, they never change width
   The distances the content must travel can't be hard-coded (they depend
   on text width, font swap and viewport), so lobby.js measures them once
   on load/resize and publishes them as the --nav-*-dx / --nav-plate-* vars.
