+// Storage is organized as follows:
+// - Global storage (session): {appDir}/session/
+// - User-specific storage: {appDir}/users/{emailHash}/{dbName}/
+//
+// This ensures:
+// 1. Different users have isolated data
+// 2. Dev and production modes have separate directories ({appName} vs {appName}-dev)
+// 3. Email addresses are not exposed in directory names (hashed)

+// getAppDir returns the application data directory path, creating it if needed.
+// Uses 0700 permissions for security (owner read/write/execute only).
+// The directory name is mode-aware: "maplefile-dev" for dev mode, "maplefile" for production.
