## 2026-07-12 - Optimize renderTaskRow DOM allocations
**Learning:** Caching unattached template nodes and instantiating them via `.cloneNode(false)` reduces DOM instantiation overhead in O(N) render loops significantly.
**Action:** Apply this optimization to other hot-path rendering elements such as rows, cells, and stack containers.

+## 2024-11-20 - Resource Discovery Optimization
+**Learning:** In purely static applications without a bundler, dynamic module imports (or late-discovered ES modules in the body) cause waterfall network requests, significantly increasing Time to Interactive (TTI).
+**Action:** Always add `` for all critical top-level ES modules in the `` of `index.html` to allow the browser to fetch and parse them concurrently with HTML parsing.
