A new 'PromptHint' pane region is now recognized alongside AbovePrompt and Pane
What
The layout logic that decides where prompt-related visibility rules apply now also checks a new region called "PromptHint", in addition to the existing "AbovePrompt" and "Pane" regions.
Why
The finding doesn't specify what content lives in the PromptHint region or what changes as a result, but it extends the same visibility framework already used for panes shown above the prompt.
