/*
    style.css
    Global and section-specific styles.
    
    OPTIMIZATION NOTES:
    - Defined a standard transition variable.
    - Optimized transitions to use 'transform' and 'opacity' for better performance.
    - Ensured project features stack nicely on mobile.
    - Removed background-attachment: fixed on .vision-section for mobile performance.
