 * The product's one backdrop for every pop-up (decision 5 October 2026).
 *
 * Bootstrap's own .modal-backdrop look: black at 50% opacity, no blur.
 * Bootstrap modals get it from .modal-backdrop below (Bootstrap's offcanvas
 * backdrop has the same default); every custom overlay (.fyi-modal, a
 * hand-rolled fixed scrim) paints var(--fb-scrim). Do not add a second
 * colour or a backdrop-filter blur.
