/*
 * FP Billing Stack Section — frontend + editor styles.
 *
 * Rounded card (heading + subtitle + infinite logo marquee + button).
 * Design source: Framer "billing stack" section (.framer-1y56018).
 *
 * Architecture
 * ────────────
 * .fpr-billing-stack               Outer wrapper — receives CSS variables from render.php.
 *   .fpr-billing-stack__card         The rounded, bordered card (background applied here).
 *     .fpr-billing-stack__header       Heading + subtitle (centered).
 *     .fpr-billing-stack__viewport     overflow:hidden clip box; optional edge fade mask.
 *       .fpr-billing-stack__track        flex row that runs the @keyframes marquee.
 *         .fpr-billing-stack__item         each logo slot (list item).
 *           .fpr-billing-stack__logo         the <img>.
 *     .fpr-billing-stack__actions      Button row (centered).
 *
 * The track is rendered twice (PHP side) so translateX(-50%) loops seamlessly.
 *
 * CSS variables (injected by render.php on the wrapper):
 *   --fpr-bs-duration   one full loop in seconds
 *   --fpr-bs-gap        gap between logos
 *   --fpr-bs-height     logo height
 *   --fpr-bs-bg         card background (solid color OR gradient)
 *   --fpr-bs-border     card border shorthand (e.g. "1px solid var(--wp--preset--color--light)" or "none")
 *   --fpr-bs-title      heading color
 *   --fpr-bs-subtitle   subtitle color
 *   --fpr-bs-btn-bg     button background
 *   --fpr-bs-btn-text   button text color
