   Sidebar — adapted from AdminKit's own sidebar component (adminkit-3.1.0)

   resting links dimmed to ~55% opacity by design and only the active
   item at full brightness — exactly the hierarchy the old adminHMD nav
   was missing. Its collapse toggle is also just a full show/hide, not a
   partial icon-only rail, which sidesteps the "every chapter row looks
   identical once the labels are gone" problem entirely. The active-state
