/* ================================================================
   VELVET THEME — User Panel  v6.0
   assets/css/user-panel.css

   BUGS FIXED IN THIS VERSION:
   ✓ Labels no longer leak outside collapsed panel
     (removed tooltip pseudo-elements that escaped overflow:hidden;
      replaced with a proper tooltip div injected by JS instead)
   ✓ Expand button now works — panel width is always wide enough
     for the button to be clickable (toggle area = full 56px column)
   ✓ Mobile no longer freezes — panel is pointer-events:none when
     off-screen, so it cannot intercept touch events
   ✓ No CSS hover expansion — toggle is click-only
   ✓ Body padding ONLY applied on desktop via @media (min-width:1025px)
