/* --- 
    CSS Refactored Version 3.0 (Orange-Yellow Theme)
    Key Improvements:
    - Swapped the primary color palette from blue to orange-yellow (#FFD93D).
    - All dependent color variables (--primary-color-light, focus rings) updated automatically.
    - Maintained all previous optimizations for contrast and code structure.
