Where 5 KB matters

A 5,120-byte file: larger than a cookie, smaller than a typical HTTP header limit. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Browser cookies	4,096 bytes per cookie	5 KB does not fit in one cookie.
Vite asset inlining	4 KB by default (assetsInlineLimit)	A 5 KB asset is emitted as a separate file rather than inlined as base64.
nginx and Apache request headers	8 KB per header line by default	5 KB fits; the 10 KB sample does not.

Testing notes for JPG

Re-saving a JPEG loses quality each time, so pipelines should resize from the original.
Photos from phones carry EXIF data including location; the samples here contain none.
