Pull Request Overview

This PR caches the acronyms from acronyms.json by loading them once at module import instead of reloading on every function call.

• Replace inline file reading in to_title with a cached variable

[Copilot]

Consider adding error handling (e.g., try/except) around the file read to gracefully handle cases when acronyms.json is missing or invalid.
