"""
Python integers have arbitrary precision, so extremely large values
like exabytes fit naturally without overflow.
Exabyte sizes:
1 EiB = 2**60 = 1,152,921,504,606,846,976 bytes
1 EB = 10**18 = 1,000,000,000,000,000,000 bytes
Python style:
- UPPERCASE names for constants
- underscores allowed in numeric literals for readability
