{#
  Kafka-UI deep-link icon macro.

  Renders a small Kafka SVG anchor that opens Kafka-UI (provectus) filtered
  to one message in a new tab. Returns nothing (empty) when the feature is
  not configured, so callers don't need to guard their own code.

  Usage:
      {% from '_kafka_ui_icon.html' import kafka_ui_icon %}
      {{ kafka_ui_icon(topic, partition, offset) }}

  The SVG path matches the one in base.html's nav header for visual
  consistency. Sized at 14px (smaller than the 20px nav icon) so inline
  placement next to a monospace <partition:offset> label doesn't dominate
  the line.
