/* ══════════════════════════════════════════════
   DETAIL PANEL  —  z:300

   KEY LAYOUT FIX:
   The NAV is position:fixed at z:400 covering the top 56px.
   To prevent the nav from covering the detail panel content,
   #detail starts at top:56px (not top:0 / inset:0).
   This means the detail panel occupies the screen area below
   the nav. The sticky #detail-top then sticks at top:0 of
   the detail panel, which is at viewport y:56px — right below
   the nav. The back button is always visible and never covered.
