"""
Phase 10 — Focus.

Generated by `makemigrations` and left as generated: one new table, nothing
existing touched.

**`started_at` and `ended_at` are `DateTimeField`s, and they are the only two
real instants in this schema.** Every other date in the app is a `DateField`, a
JSON day key or — for Calendar — a `CharField` holding wall clock with no zone.
A focus session is a measured interval whose length is the whole point, so it
is the one thing `USE_TZ = True` is actually for. `models/focus.py` argues it.

There is no `paused_at` column: a running session lives in the client, and a row
that arrives from the server is finished.
