/**
 * 609 Studios Chatbot - widget styling
 *
 * Vanilla CSS, ingen build-process. Använder CSS custom properties så att
 * Mattias kan justera färger utan att redigera flera ställen.
 *
 * Brand: svart och vit bas med Amber Rust (#a94828) som accent.
 * Typografi: Isidora Sans för rubriker, Source Sans Pro för text.
 * Faller tillbaka till system-stack om brand-fonts inte finns laddade.
