 ## 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.
+## 2026-07-19 - Redundant resource hints and missing modulepreloads
+**Learning:** Placing a `<link rel="preload">` for a stylesheet immediately before its actual `<link rel="stylesheet">` tag is redundant and provides no benefit, as modern browser preload scanners will detect both simultaneously. Valid resource hinting optimizations include using `<link rel="modulepreload">` for scripts located at the bottom of the `<body>`.
+**Action:** Remove redundant CSS preloads when the stylesheet is in the `<head>` and use `<link rel="modulepreload">` for ES modules at the end of the body to start fetching them early.
