"""Quick Edit must report image-generation failures in plain language.

Three cases are covered, each asserting both layers:
  1. image server unreachable / timed out  -> fixed "offline" sentence
  2. server up but generation switched off -> fixed "disabled" sentence (HTTP 503)
  3. anything else                         -> the server's own short reason
