+## 2024-04-27 - Cache Prefixless IconifyIcon Lookups
+**Learning:** Prefixless icon lookups in `IconifyIcon` invoke an `Object.entries(iconSets)` loop and multiple string parses per icon render, causing an O(N) lookup bottleneck when rendering many icons.
+**Action:** Always wrap frequent, pure, synchronous lookup functions (like icon resolving) in a global memoization cache map to make them O(1), significantly reducing CPU overhead during heavy UI rendering.
