🎯 Use case

This file lives under “utils/”, which covers cross-cutting helpers (shell, tempfiles, settings, messages, process input, …). On the API surface it exposes intersperse, count, and uniq — mainly functions, hooks, or classes.

Generated from folder role, exports, dependency roots, and inline comments — not hand-reviewed for every path.
