{# Detail-page Keep/Pass/Untrack action bar (ARG-184).

   Rendered both by item_detail.html (initial page load) and as the HTMX
   swap target for POST /items/{id}/keep|pass?context=detail,
   POST /assets/{id}/untrack?context=detail, and
   POST /assets/{id}/handoff?context=detail. Passing ``context=detail`` on
   those routes is what makes them return THIS partial instead of the feed's
   ``_feed_card.html`` — the detail page has exactly one card on screen, so
   it needs its own standalone fragment rather than a full card re-render.

   Every detail mutation swaps the whole ``#detail-actions-<id>`` wrapper
   (banner + bar) via outerHTML, so the handoff banner and the action bar can
   never drift into an inconsistent state (ARG-209): a handoff archives the
   predecessor, and the re-rendered wrapper drops the banner and shows the
   Archived bar in one swap. The inner ``#item-actions-<id>`` div is kept so
   existing selectors/tests still resolve.

   Once an item is Kept, the Keep button is replaced by Untrack (mirrors the
   portfolio's one-way "release from Keep" action) rather than staying a
   togglable ✓ Keep — Pass stays a toggle in both states, same as the feed. #}
{# ``action_context`` is ``detail`` on the item page and ``event`` on the event
   page (ARG-243); it rides along on every POST so the response re-renders
   this bar for the right page (the event page has no 관련 신호 to refresh). #}
