/* Persistent sidebar (responsive nav, 1 Oct 2026). Hidden below 900px --
   phones keep the existing hamburger -> full Admin-menu-screen flow
   untouched, since the item table needs the width more than a permanent
   nav rail does. At >=900px (PC/tablet) it docks to the left instead.
   Top offset is an approximate padding (not a measured header height) --
   the background color matches the header's, so a few px of difference
   is invisible rather than a visible seam; nudge the 76px if you see a
   gap or overlap once this is live. */
