{# Settings → Translation (issue #133): the installation's preferred target
   language (a string override: "Use installation setting" writes NULL, a
   language writes the override) and the auto-translate tri-state. Validated
   through the shared translation_flags_ok invariant (auto-translate needs a
   target language); the LLM dependency is a runtime gate surfaced as an honest
   note, not a save-blocker. Self-contained: renders from _settings_context. #}

   out of date and you can re-translate from the run page. Changes here apply to
   your next run or job, no restart needed.</p>
