       AUTOMATIC RESPONSIVE SCALING WITH BREAKPOINTS
       ================================================================
       The scale automatically adjusts based on screen width.
       Customize the breakpoints below to fit your devices.

       Current breakpoints:
       - Small (up to 1024px):     1.2x scale (mobile, tablets)
       - Medium (1025-1600px):     1.0x scale (laptops, small desktops)
       - Large (1601-2400px):      1.3x scale (large desktops)
       - Extra Large (2401-3200px): 1.6x scale (large monitors)
       - Huge (3201px+):           2.0x scale (4K TVs, huge screens)

       ANIMATION TIMING CONFIGURATION

       To adjust animation speed globally, modify these values.
       All durations are in seconds.

       To slow down by X%: multiply each value by (1 + X/100)
       To speed up by X%: multiply each value by (1 - X/100)

       Example: To slow down by 20%, multiply all values by 1.2
