How would you implement asynchronous file I/O using aiofiles alongside an async context manager, to avoid blocking the event loop during file operations?

Standard Python file I/O is BLOCKING (no native async file API in the standard library), so aiofiles wraps file operations in a thread pool internally while exposing an async context manager interface (`async with aiofiles.open(...) as f:`), letting file reads/writes coexist with other async work without blocking the event loop.

import aiofiles

async def read_file_async(path):
    async with aiofiles.open(path, mode="r") as f:
        content = await f.read()
    return content

async def main():
    content = await read_file_async("data.txt")
    print(content)
