                                The confidence belongs to the provider chosen right next to it, so both share one row.
                                It uses the icon trigger, like the chat does, so this row ends the same way the profile
                                row below it does: a field followed by one compact icon button.
                                Do not add a margin to that button to "correct" its height: a dense outlined select with
                                a label carries margin-top 8px and margin-bottom 4px of its own, so centring the boxes
                                already lands within a few pixels of the visible frame, and any added margin makes it
                                worse. Baseline alignment does not work here either, because the wrapper below takes
                                its baseline from its last line box, which sits under the input.
