  The file moved between being opened and being saved -- another editor, a
  build, a checkout.

  Three answers, and none of them is silent. Never save over somebody else's
  change without saying so; never throw away what was typed here without saying
  so either. What you wrote is held in the form below, so Overwrite is one
  click and not a retype.

  Sent at 200 rather than 409 on purpose: htmx does not swap an error status,
  and a card offering three buttons cannot be offered from a response the panel
  will not render.
