Record that somebody is away

"I am away 20 Aug – 3 Sep."

One stretch during which a person is not to be given a shift.

Org-wide, not per team: being on holiday is a fact about a person, and somebody on two teams is away from both. Per team, the window has to be written twice, and forgetting the second is the exact failure this prevents — a page landing on somebody who is on a beach.

Absolute micros, like an override. Recurrence is a calendar feature, and a schedule that guesses which Fridays somebody meant guesses wrong at 3am.
