"""Write a day of invented food and workout logs for the offline end-to-end run.

The real logs are the operator's day, kept by diet_guard and screen_locker
outside this repository; the e2e run must not read them, and could not
count on what they hold. This writes one entry of each under today's
Warsaw date -- the day the bot will ask for -- so the two scenarios have
a known word to look for.
