Where 2 MB matters

A 2,097,152-byte file: exactly the default upload limit of PHP, and twice the default of nginx and Spring Boot. These are the default limits a file of this size is useful for testing:

System	Limit	Note
PHP	2 MB per uploaded file by default (upload_max_filesize)	A file of exactly 2 MB is accepted; one byte more is refused.
nginx	1 MB by default (client_max_body_size)	Rejected with 413 Request Entity Too Large.
Spring Boot multipart	1 MB per file by default (max-file-size)	Rejected unless the property is raised.
Django	2.5 MB in memory by default	2 MB is held in memory; the 5 MB sample is streamed to a temporary file.

Testing notes for Markdown

Markdown may contain raw HTML, so anything that renders user-supplied Markdown needs an HTML sanitiser.
Tables are an extension rather than part of CommonMark, so renderers differ on whether they appear.
