/* ===== Modernized Left Sidebar ===================================================
       Design goals:
         - Light neutral background (#f8f9fb) — calm, professional, not dominant
         - Red (#dc2626) used as accent only: active item bg tint + icon/text color
         - 280px width, 44px item height, 8px rounded corners
         - Compact profile header (replaces the old tall toolbar)
         - Small-caps section labels instead of bold md-subheader
         - Smooth hover / active transitions
    ================================================================================ */
