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
Ethernet	1,500 bytes (typical MTU)	A 1 KB payload fits in one packet with its headers.
Browser cookies	4,096 bytes per cookie	1 KB is well inside the limit; the 5 KB sample is over it.

Testing notes for RTF

Two MIME types are in use, application/rtf and text/rtf, and allow-lists should recognise both.
RTF readers must skip groups they do not understand; a parser that fails on unknown control words is not conformant.
