## Remarks

Every one of these comes from the SDK, not from your own handlers: a route or
handler that is not there, a token that is missing or does not verify, a missing
event id, a body that is not JSON or is over 1 MB, a webhook Tappify rejected,
and the catch-all for an error a handler let escape. Throw a `TapServerError`
with a code of your own for anything your server decides.
