{# Server-rendered recursive tree view of one LogixNG program.

   Expected context:
     * name      -- the LogixNG system name (string, URL-safe)
     * root      -- the LogixNG Node tree (jmri_logixng.LogixNG)
     * logixng_is_container, logixng_list_slots, logixng_single_slots
       -- helpers from jmri_logixng.tree_ops, exposed by the view.

   The template renders the root as a nested set of cards -- one per
   node, indented by depth. Each card shows:
     * the type_tag + user_name + id (muted)
     * Edit button -> htmx-swaps in an edit form fragment
     * Add-child dropdown (for container nodes)
     * Delete button (non-root)
     * Nested children rendered via a Jinja include-self recursion.
