+Config Manager Module
+=====================
+
+This module provides **thread-safe** centralized management for application
+configuration in YTSage. It handles reading, writing, and managing settings
+stored in a JSON file, with support for nested keys via dot notation.
+
+Thread safety is ensured using a reentrant lock (`RLock`), so multiple threads
+can safely access or modify settings concurrently.
+
+Features
+--------
+- Thread-safe operations for getting, setting, and deleting configuration values.
+- Loads settings from a JSON config file (`APP_CONFIG_FILE`).
+- Creates the config file with default values if missing or corrupt.
+- Retrieves, sets, and deletes settings using dot-separated keys.
+- Provides safe error handling with logging instead of raising exceptions.
+- Persists updates back to disk automatically.
+
+Usage
+-----
+from src.utils.ytsage_config_manager import ConfigManager
+
+# Load settings (auto-loads if not already loaded)
+download_path = ConfigManager.get("download_path")
+
+# Update a value
+ConfigManager.set("download_path", "D:/Downloads")
+
+# Retrieve nested value
+last_check = ConfigManager.get("cached_versions.ytdlp.last_check")
+
+# Delete a key
+ConfigManager.delete("cached_versions.ffmpeg.path")
+
+Design Notes
+------------
+- Settings are stored in `ConfigManager.settings` (a dict).
+- Default values are defined in `ConfigManager.default_config`.
+- All modifications trigger a save (`_save`) to keep JSON in sync.
+- Logs actions and errors using the app's central logger.
+- Uses `RLock` to allow safe concurrent access from multiple threads.
+
+Exceptions
+----------
+- Any issues during file I/O (permissions, disk errors, JSON corruption)
+  are caught and logged. The application continues running with defaults
+  when possible.

+Localization Manager Module
+==========================
+
+This module provides centralized localization support for YTSage application.
+It handles loading language files, switching languages, and retrieving localized strings.
+
+Features
+--------
+- Thread-safe operations for getting localized text
+- Fallback to English when translation is missing
+- Support for multiple languages via JSON files
+- Dynamic language switching without restart
+- Nested key support with dot notation
+
+Usage
+-----

+text = LocalizationManager.get_text("download.ready")
+button_text = LocalizationManager.get_text("buttons.download")
