Where 25 KB matters

A 25,600-byte file: the size of a small web image or a short document. These are the default limits a file of this size is useful for testing:

System	Limit	Note
TCP initial congestion window	About 14.6 KB (10 segments)	25 KB needs at least two flights of packets on a new connection.
Base64 encoding	Adds 33 percent	A 25 KB file becomes about 34 KB inside JSON or an email.

Testing notes for TOML

Arrays of tables use double brackets, [[name]], and are easy to confuse with ordinary tables.
Dates are a native type, so a value such as 2026-01-01 is not a string unless it is quoted.
