Where 1 KB matters

The smallest practical test file: 1,024 bytes, small enough to travel in a single network packet. These are the default limits a file of this size is useful for testing:

System	Limit	Note

Checking sanitisation of rendered HTML

Tables are an extension rather than part of CommonMark, so renderers differ on whether they appear.
