+# @toolctrl/shared
+
+Cross-cutting shared types and utilities that are not app-specific.
+
+This package starts intentionally empty in Phase 3 so future moves can happen only when ownership is clear. Do not place web, API, worker, provider or database-specific code here.
+
+Good candidates:
+
+- Pure TypeScript types shared across app boundaries.
+- Small dependency-free utility functions.
+- Constants that are not owned by config, i18n, database, auth or queue packages.
