- Add EachSeq[T](iter.Seq[T], fn) for iterator-based template rendering - Use slices.Collect(maps.Keys()) + slices.Sort for deterministic attr output - Use strings.SplitSeq in codegen TagToClassName and path parsing - Use range over int in layout and pipeline loops - Refresh go.sum Co-Authored-By: Gemini <noreply@google.com> Co-Authored-By: Virgil <virgil@lethean.io>
