/* ==========================================================================
   LP03 · UNIT 5 · GET STARTED WITH GUIDED ONBOARDING — choose your path
   --------------------------------------------------------------------------
   Navy section. Centered copy, then a start node whose line forks into two
   paths, each ending at a photo card: Self-service guide · Assisted
   onboarding (the copy's own two options).
   The choice is a pair of NATIVE radio inputs (keyboard + screen readers
   for free); the cards are their <label>s. Lighting the chosen path is
   pure CSS (:has(:checked)), so it works without JS. onb.js only adds the
   entrance and lights the chosen card's guided steps in sequence.
