/**
 * FBT Styles - Frequently Bought Together
 * YayBoost plugin. Minimal e-commerce styling.
 *
 * Layout: a "current product" card, a titled add-on section of selectable
 * cards, then the bundle total and a full-width button. Every rule is scoped
 * under .yayboost-fbt for theme safety, and nothing sets a fixed or minimum
 * width — the same markup is reused inside the post-add-to-cart popup dialog
 * (see assets/css/fbt-popup.css).
