+  pre-commit, the `LEFTHOOK_FILES` env var scopes to the staged
+  files matching `*.{ts,tsx,js,jsx,mjs,cjs,json,jsonc,yaml,yml,md,mdx}`.
+  Built-in `sortPackageJson: true` keeps `package.json` keys
+  alphabetized (replaces the former `sort-package-json` tool).
+  Built-in import sorting (enabled via `sortImports: true`) replaces
+  any external import-sort plugin.
 - `check:tsc`: `tsc --noEmit`.
 - `check:cspell`: `cspell lint ${LEFTHOOK_FILES:-.}` — walks the
   project root by default; from lefthook, only the staged files.
-- `check:package`: `sort-package-json --check`.
 - `check:outdated`: `check-outdated --ignore-pre-releases --ignore-packages @oxfmt/binding-*,@oxlint/binding-*`. The oxc native bindings are declared as `optionalDependencies` so the correct one is selected per platform automatically; the `*`-platform bindings show as "not installed" on the current platform and are explicitly ignored here.
