/* ==========================================================================
   LUFLY - Component: navbar ("Machined Glass")
   --------------------------------------------------------------------------
   One glass slab plus a machined side spine:
     slab    brand · instant search · utility actions  (a single row, always
             64px tall, so the bar never grows)
     spine   a fixed vertical rail on the inline-start edge: the crooked
             machined line (hover target), the quick links read downwards, a
             knurled foot and the scroll progress. Approaching the line
             unfolds the geometric index drawer out of the spine.
   Below 1024px the spine gives way to a small bloom button that opens a
   chamfered bottom sheet whose petals unfold and whose links stagger in.

   Rules of the house:
     * every colour resolves through a token from design-system/style.css
     * only transform / opacity / clip-path / background are animated
     * no layout thrash on scroll - the slab keeps a fixed height, the spine is
       fixed to the viewport and content is offset from it once, on load
   ========================================================================== */
