{#
  What `/usage` shows.

  Two different numbers, deliberately kept apart. **Used** is how full the
  window is right now -- one reply's prompt plus its completion, which is what
  decides when compaction fires. **Spent** is everything this conversation has
  cost end to end, which is larger and grows forever: a three-round reply pays
  for its prompt three times but only ever occupies the window once.

  Anything derived from an estimate wears a `~`, because `services/tokens.py`
  counts four characters to a token when an endpoint reports nothing, and a
  precise-looking figure that is a guess is worse than an obvious guess.
