/*
 * Marketing UI Stack card (Content Component)
 * Webflow classes: home_promo_card-wrapper / home_promo-card
 * Live: https://www.marta-platform.com/promotion-trigger-engine
 *
 * Structure (VERIFIED FROM WEBFLOW):
 *   .mkt-stack                         /* .home_promo_card-wrapper
 *     .mkt-stack-card                  /* .home_promo-card
 *       .mkt-stack-card__text          /* .promo-text_wrapper
 *         title, body, optional chip
 *       .mkt-stack-card__pattern       /* .layout-image-wrapper.is-banner-new
 *         img.mkt-stack-card__pattern-img  /* .image-8
 *
 * Tones (VERIFIED FROM WEBFLOW class names):
 *   data-tone="pink"          → .is-first        Pink/500
 *   data-tone="pink-soft"     → .is-second-new   Pink/100
 *   data-tone="violet-soft"   → .is-tirty-new    Violet/200
 *   data-tone="blue"          → .is-four         Blue/500
 *   data-tone="violet"        → .is-five         Violet/500
 *
 * Sticky offsets follow stack order (nth-child), not tone, so the cascade
 * still works when tones are reordered.
 *
 * Webflow combo tops, one-line titles, step 4.5rem:
 * is-first 8rem, is-second-new 12.5rem, is-tirty-new 17rem, is-four 21rem,
 * is-five 25.5rem, is-six 30rem, is-seven 34.5rem.
 * is-five was 0.5rem and cards 6–7 reused is-first / is-second-new, so they
 * stuck on the same offset and collapsed. These pages use two-line titles,
 * so the prototype peek is padding + two title lines + 10px. IMPLEMENTATION DECISION.
 *
 * Scroll scale (VERIFIED FROM WEBFLOW IX2 "Cards 2" / a-13):
 *   SCROLLING_IN_VIEW, keyframe 54 → scale 1, keyframe 100 → scale 0.8,
 *   smoothing 90. Implemented in stack-card.js.
 *
 * 991 / 767 / 479 are existing Webflow breakpoints, not Figma tokens.
 *
 * NOT DEFINED (Webflow card + Figma DS):
 *   hover / focus / pressed
 *   Figma has no Stack card / home_promo component set
