 ## 2026-02-15 - [Semantic Form Labels]
 **Learning:** Even with clear visual labels, missing `for` attributes on `<label>` elements prevents proper association with inputs for assistive technologies.
 **Action:** Explicitly link labels and inputs using `for` and `id` attributes in all form components.

+## 2026-02-21 - [Surgical Fixes for Mixed Line Endings]
+**Learning:** In repositories with mixed line endings (CRLF/LF), using global reformatting tools like `dos2unix` creates large, noisy diffs that violate "micro-UX" constraints. Targeted `sed` commands or precise search blocks are preferred for minimal, safer changes.
+**Action:** Use `sed` for single-line tag fixes and keep `replace_with_git_merge_diff` blocks as small as possible.
