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 KML

KML can pull in remote content through network links and icon URLs. An importer should not fetch them blindly. The samples here refer to nothing outside the file.
Longitude comes first. Reading the pair the other way round moves every point to a different part of the world.
