/* 
   Since JS controls transform directly (x, y, rotation), 
   CSS animations on 'transform' will conflict.
   Optimized Approach: 
   - Animate a child element for the visual flare 
   - OR use an 'initial-scale' property in JS 
   - OR use a wrapper div where the wrapper is moved by Physics, and the inner div animates.
   
   Let's stick to the current structure (<a> tags). 
   The JS "UpdatePhysics" overwrites 'transform' every frame.
   
   Solution:
   We will add the "teleport" effect via a CSS filter and Opacity, 
   and maybe a 'scale' variable in the physics engine, rather than CSS keyframes on transform.
   
   But we can use a ::before pseudo element for a flash effect!
