/* Site-wide fix: make Drupal checkboxes and radios visible again.
 *
 * Bootstrap 5 draws its own box instead of the browser's: `.form-check-input`
 * sets `appearance: none` and then paints the box with `--bs-border-color` on a
 * fill of `--bs-body-bg`. DXPR points `--bs-border-color` at its own
 * `--dxt-color-graylighter`, which in this site's palette is around #ededed, and
 * `--bs-body-bg` at the page background, which is white. The result is a 13-pixel
 * white square with a border you cannot see on a white page.
 *
 * It was found on the goods receipt form, where a whole column looked empty and
 * the one control that closes a short delivery had no visible checkbox. But it
 * was never about that form: it is every checkbox on the site, including the ones
 * on the stock board that decide what gets bought.
 *
 * Only the unchecked box is touched. Bootstrap's checked state already fills the
 * box with the accent colour and draws a white tick, and that reads fine. The
 * selector carries three classes and pseudo-classes on purpose, so it wins over
 * `.form-check .form-check-input` without needing `!important`: module CSS loads
 * before theme CSS, so on equal specificity the theme would win.
