Problem

When an opening is invalidated (opponent deviated beyond assumptions), the OpeningSuggestion component disappears because the render condition checks !activeOpeningState.invalidated. The player sees the suggestion bar vanish with no explanation of why.

Fix

Show a toast or brief overlay when invalidation happens: "Opening disrupted — opponent deviated." Options:

Check invalidation state in the handleCommit flow and show a toast
Render a brief "Opening disrupted" message in place of the suggestion bar for one turn
Use a brief status message that auto-dismisses
