   /v2/css/utilities.css
   Mini Bootstrap-compat utility layer.  Provides the handful of
   Bootstrap classes we still depend on in markup, so we can drop
   bootstrap.min.css entirely without rewriting every class= attr.

   Covers (audited from search-v2.html):
     - Text:    text-center, text-danger
     - Grid:    container, row, col-*-N
     - Buttons: .btn (generic styling — page-specific .btn-buy,
                .btn-search override in search.css)
     - Form:    form-control, form-group
     - List:    list-group
     - Spacing: mb-0
     - A11y:    sr-only

   Total: ~80 lines.  Saves ~155 KB by dropping bootstrap.min.css.

   Loaded by: every page that previously included bootstrap.min.css
