   PRINT-SPECIFIC CSS FOR PDF OUTPUT
   ========================================
   
   This file handles special formatting when printing or exporting to PDF.
   
   Features:
   1. Hide interactive elements (dropdowns, popups, CAS windows)
   2. Flatten tab-set/tab-item structures for print
   3. Hide answer and solution directives in main content
   4. Collect and display all answers at the end
   5. Hide CAS-popup buttons
