/**
 * Starby Karta — frontend.
 *
 * Mobil-först. Layout: stack på <1024px, sida-vid-sida på ≥1024px.
 * Bottom sheet på touch-enheter, sidobild på desktop.
 *
 * All visuell anpassning sker via CSS-variabler (sätts inline av Renderer
 * från BB-modulens fält) och modifier-klasser. Default-värden bakas in här
 * så shortcode / direktanrop får sensibla värden utan extra style-attribut.
