+@*
+    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 the row ends in 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.

     @* ProviderSelection marks its select as flex-grow-0, and that utility is declared !important, so StretchItems
