Dev, PN/Corax CoLAB: [performance improvement]
💡 What: Implemented debounce and throttle utilities for high-frequency window events (`resize`, `scroll`, `mousemove`), optimized Web Worker memory allocation (`Float32Array`), and added `aria-label` accessibility attributes to buttons.
🎯 Why: High-frequency DOM events cause massive main thread blocking during user interactions. Repeated large array instantiations in the Web Worker affect garbage collection. Buttons missing `aria-label` hurt screen reader accessibility.
📊 Impact: Considerably reduces layout thrashing, ensures smooth 60fps scrolling and resizing, improves Web Worker memory performance, and enhances compliance with accessibility standards.
🔬 Measurement: Verified via e2e Playwright tests. Smooth animations during resize and scroll, and proper `aria-label` reporting in accessibility trees.
