{#
── Model-based relationship combobox ────────────────────────────────────────
Queries the model directly via the panel's GET /_model_search endpoint.
The nuruCombobox Alpine component is registered in layout.html's alpine:init
listener — nothing extra is needed here.
Field attrs:
field.model — SQLModel class (provides the model name in the URL)
field.value_field — attr used as FK value (default: 'id')
field.label_field — attr shown as label (default: str(record))
field.relationship — attr on *this* record for detail-view display only
Context variables (injected by macros/form_item.html):
current — current FK value (int / str / None)
has_error — bool
errors — dict { field_key: message }
input_class — pre-built Tailwind input classes
panel_prefix — URL prefix of this admin panel
#}

{# Hidden input carries the FK value on form submit #}
{# Loading skeleton — shown only during the initial fetch #}
{# Search input + clear button #}
{# Spinner shown during remote fetches (not the initial load) #}
{# Dropdown — teleported to to escape any overflow:hidden ancestor.
@mousedown.prevent on options keeps focus on the text input (preventing
@blur from firing before pick() runs). #}
