   Container / Section / Columns). Kept local to this package (not in
   shared.tsx, which is foundation/import-only) since it's just DRY-ing the
   identical JSX block across those 3 components rather than a genuinely
   cross-package reusable control. Mirrors the equivalent helper in the
   media package (mediaBoxModel.tsx) -- same shape, independently duplicated
   per-package by design (packages are developed and merged in parallel).
