/* Timeline Cards — pure CSS (no HubL)
   Heading / paragraph inherit HubSpot theme styles.
   Eyebrow uses existing .eyebrow module styles.
   Intro CTA uses Elements button classes from the one-button module.
   Module CSS only handles layout, timeline rail, and card chrome.
   Mobile (<992px): intro CTA sits beneath the card stack.
