A measurement table in your shadcn Dialog that morphs out of a quiet link beside the size label, and back into it (Motion; a fade under reduced motion). Centimetres and inches with tape-honest rounding, the shopper's selected size marked and announced, ranges and size equivalents (EU 38) in the same table, and a size column that stays put while the measurements scroll sideways on narrow screens. Composed from parts that share the unit through context.
