{# Inline take-history panel for one deck/part.

   Lazy-fetched via HTMX from
   ``GET /decks/{course}/{section}/{deck}/takes?part=N`` and rendered
   inside an additional ``<tr>`` directly under the deck row. The panel
   refreshes itself on ``sse:job`` events so a retake-in-progress shows
   up without the user toggling the panel.

   Inputs:
     deck_name        — original (un-sanitized) deck name; rendered in the header
     part             — part number this panel is showing
     active           — ``TakeFileInfo`` for the active take, or None when
                        no state record exists for this part (the panel
                        then renders only superseded history).
     takes            — list of TakeFileInfo for superseded takes
     panel_locked     — True when the session has this exact deck armed/
                        recording. Restore buttons render disabled and
                        the column header is replaced by an info note.
     restore_url_for  — callable(take) → URL for the restore POST.
