+Carbon _Actionable notification_ + APG _Alert_): **announce the change politely and move
+focus to a stable neighbour.** Concretely, the builder writes "Applied: `<label>`." to a
+visually-hidden `role="status" aria-live="polite"` node and moves focus to the guidance
+region if any hints remain, else the surrounding pane (`tabIndex={-1}` anchors, focused only
+programmatically — no visible ring). Advisory hints themselves don't _grab_ focus (APG: an
+alert "must not affect keyboard focus"); the fix's remedy lives in a **low-emphasis ghost
+button** beside the advice (Carbon: inline actionable → ghost button, wraps under the body
+on narrow widths), an _offer_, never a forced change.
