/* ============================================================================
   DataTables & Corpus Table - From Legacy md3-components.css
   ============================================================================
   TRANSFERRED FROM: static/css/md3-components.css (Lines 2200-2700)
   
   STATUS: ⚠️ Uses legacy MD3 tokens (--md3-*), needs migration to --md-sys-*
   
  ⚠️ THEME BEHAVIOR: DataTables should follow MD3 theme tokens
  - Removed forced light-mode overrides for dark mode compatibility
  - Tables now adapt to dark/light theme via CSS variables when possible
   
   Contains:
   - Corpus table structure (#corpus-table)
   - DataTables wrapper customization
   - Export buttons (CSV, Excel, PDF)
   - Pagination styling
   - Audio cell layouts
   - Token ID styling
   - Spectrogram overlay
   
   IMPORTANT: Table container expands to right as needed, beyond parent constraint.
