/* ==========================================================================
   Launch Labs — Section: "How it works"
   Sits directly after the philosophy section, same black surface. Three
   equal steps in a single horizontal row, joined by small red arrows, then
   a centered reassurance statement below.

   Structure: section shell -> centered intro (eyebrow, heading) -> row of
              three cards with an arrow in each gap -> closing statement,
              given extra room so it reads as a conclusion rather than
              another block underneath -> a "Start SHAPE" CTA closing the
              section.

   Reveal, via js/process.js: the section fades in once (.is-visible) —
   intro first, then, after a deliberate pause (0.6s), the three cards
   (and the arrows between them) stagger in below. Only once that stagger
   has finished, plus a further pause, does the closing statement (red
   line + sentence) get its own .is-visible, timed via JS rather than a
   second scroll trigger, so it's always "boxes land, then the line
   runs," never racing ahead on a fast scroll or finishing before the
   visitor has actually scrolled the section into view. The CTA button
   is a child of .process__closing, so it inherits that same .is-visible
   trigger and simply staggers in last (see .process__cta below).
