   Czar Floors — AI preview kit (scripts/czar-ai-preview.js)
   Shared by the product-page "See It in Your Room" window, the
   See It in Your Room page and the Floor Designer.

   Controls use stock Bootstrap 5.3 classes (btn-group/btn-check,
   accordion + the site's cz-accordion, form-select, form-check,
   btn-outline-*, alert, spinner). This file holds ONLY what Bootstrap
   has no class for. Maroon is reserved for the primary action (.btn-cz).
