/*
 * Bootstrap 3 -> 5 compatibility layer.
 *
 * The app moved to Bootstrap 5.3. Most of the markup needed no change, because the class names that
 * dominate these views survived: col-md-*, col-sm-*, row, container, table, form-control, btn,
 * btn-primary/danger/success, alert-*, text-*, modal, modal-dialog/content/header/body/footer and the
 * modal show/hide events are all still Bootstrap 5.
 *
 * A bounded set of classes did go away. Rather than hand-edit ~500 references across 31 views with no
 * test coverage, they are defined here in terms of Bootstrap 5. Each block says what it replaces, so
 * views can be modernised piecemeal later and the corresponding block deleted.
 *
 * NOTE: this is a shim, not a finished markup migration. The stack is genuinely Bootstrap 5 - it is
 * the view vocabulary that is still partly 3.x.
