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 PPTX

Converters differ in font substitution; the same deck can reflow when a font is missing.
Presentation size is dominated by embedded media, so limits tuned for documents are often too small for real decks.
