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.
Vercel Functions	4.5 MB request body	Accepted, including as base64 at about 2.8 MB.

Testing notes for ZIP

An archive can expand to far more than its own size. Enforce limits on total extracted bytes and entry count to guard against zip bombs.
Entry names may contain "../". Extracting without validating paths lets an archive write outside the target folder.
