"""Request and result payloads this library owns.

Both `advanced_library.py` (which serves the request) and `nodes.py` (which sends it)
import this module, so the payload classes they use are the same objects. The library
directory is on `sys.path` by the time either file loads, which makes the plain
`import colorspace_events` work.

Give this file a distinctive name. Every library directory lands on the same `sys.path`,
so a generic name like `events.py` risks resolving to a different library's file.
