 .SYNOPSIS
-  Sets up git pre-commit hooks for this repo (pre-commit framework).
+  Sets up git hooks for this repo (lefthook).
 
 .DESCRIPTION
-  Installs the `pre-commit` package if missing and runs `pre-commit install`
+  Installs `lefthook` if missing and runs `lefthook install`
   so the lint/format/unit-test checks run automatically on every `git commit`.
   Works on Windows PowerShell 5.1 and PowerShell 7+.
