Where 10 MB matters

A 10,485,760-byte file: over the default limits of PHP, API Gateway and Spring Boot requests. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Amazon API Gateway	10 MB payload	A 10 MB file in a multipart or base64 body is over the limit.
Spring Boot multipart	10 MB per request by default (max-request-size)	Exceeded once form overhead is added.
PHP	8 MB POST body by default (post_max_size)	Rejected before the script runs.
Amazon S3 multipart upload	5 MiB minimum part size	This file splits into exactly two minimum-sized parts.
Email attachments	Commonly 20 to 25 MB per message	10 MB fits, at about 13.3 MB once encoded.

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.
