   CSS Variables - Shadow System & Theme Configuration
   =====================================================
   
   SHADOW SYSTEM OVERVIEW:
   This table component uses a comprehensive shadow system to provide 
   visual boundaries between fixed and scrollable areas:
   
   1. HEADER ROW SHADOWS: Applied to all sticky headers to separate them
      from scrollable content below
      
   2. PINNED COLUMN SHADOWS: Only applied to the LAST pinned column to 
      create a clear visual boundary between fixed and scrollable columns
      
   3. UI ELEMENT SHADOWS: Consistent shadow styling for dropdowns, modals,
      tooltips, and interactive elements
      
   The shadow system is automatically applied when using ExceLikeTable
   with no additional configuration required.
   ===================================================== */
