+## 2024-06-08 - IconifyIcon Performance Bottleneck\n**Learning:** The IconifyIcon component was doing O(N) array iteration lookups over all icon sets on every render for prefix-less icons, which is a performance bottleneck in React 19 / MUI applications.\n**Action:** Use a Map to cache iconData resolution to prevent performance-blocking lookups.
