- A seemingly minor CSS animation, specifically 'loading dots', can cause significant ongoing CPU usage, dropping from 10–15% to near 0–1% after removal.
- Persistent high CPU in a real-time dashboard, despite optimizations, was traced to a continuous animation that forced browser layout and repaint work.
- Replacing the animated loading indicator with a static ellipsis eliminated unnecessary CPU load, aligning with the product's lean, efficient design philosophy.
- The incident underscores the principle that every element in software must justify its existence, prioritizing performance and user experience over decoration.
