feat(destinations): the After Year 11 section

Question cards over one bar, with the cards acting as a lens on the bar
rather than a summary beside it — focusing a card dims everything it is
not made of, so the grouping we chose is inspectable rather than asserted.

The bar renders only when canRenderBar allows it. Where a category is
withheld the section says so and shows the table instead: the categories
sum to the cohort, so a bar drawn from the published segments leaves a
gap whose width is the withheld figure.
