/* ==========================================================================
   Bootstrap-5-compatible grid and form controls, built on our design tokens.

   The class names are Bootstrap's on purpose — row, col-md-6, form-label,
   form-control, form-select, form-check, invalid-feedback — so the markup reads
   exactly like a Bootstrap form and anyone familiar with Bootstrap can work on
   it. The implementation is ours, at roughly 4KB instead of ~160KB, which
   matters on a low-end Android over 3G and keeps the site visually one product
   rather than two.

   Only the subset this form actually uses is implemented.
