Where 200 KB matters

A 204,800-byte file: twice the default body limit of most API frameworks, and a common cap for photo and signature uploads on application forms. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Express body parsers	100 KB by default	Rejected with 413 unless the limit is raised.
Amazon DynamoDB items	400 KB per item	200 KB fits, even after base64 encoding takes it to about 273 KB.
Azure Service Bus, Standard tier	256 KB per message	Fits as raw bytes, but not once base64-encoded.

Testing notes for Markdown

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