ByteConstants class abstract

Named constants for common byte sizes.

Provides easy access to well-known sizes for media, cloud services, and common file size limits.

Example:

// Check if file exceeds GitHub's limit
if (fileSize > ByteConstants.githubMaxFile) {
  print('File too large for GitHub!');
}

// Compare to media capacity
print('This would fill ${fileSize.bytes / ByteConstants.cd700.bytes} CDs');
