The Matrix

wake up... the matrix has you

``` Wait, I need to reconsider the trail rendering. Drawing random glyphs for each trail position every frame creates a chaotic shimmer — which is actually a desirable Matrix effect. But the leading char should be persistent and bright. Let me also make sure the trail doesn't redraw over the same positions causing too much brightness. Actually the current approach works but let me refine: the issue is that with the fade rect at 0.055 alpha, trails will naturally fade. But I'm also explicitly drawing each trail char. This double-approach is fine — gives that classic look. Let me just verify the rendering is clean. The code looks good. Let me finalize.
