init_shared.py

#init_shared.py
# Description:
# This file, init_shared.py, is responsible for initializing and providing access to shared data across different modules in the Ragnar project.
#
# Key functionalities include:
# - Importing the `SharedData` class from the `shared` module.
# - Creating an instance of `SharedData` named `shared_data` that holds common configuration, paths, and other resources.
# - Ensuring that all modules importing `shared_data` will have access to the same instance, promoting consistency and ease of data management throughout the project.

import sys

# Pager mode: ensure bundled lib/ is on sys.path before any other imports.
# PagerRagnar.py also does this, but init_shared may be imported first by
# other modules (orchestrator, display, etc.) so we must handle it here too.
