/* ---------- 02 How we work: one project through five steps, AI and team at each ----------
   Static everywhere by default. On wide screens with motion (site.js adds .is-live) it plays by itself and loops:
   the project travels along the line, each step lights up as it arrives, its AI line types out, then the team signs off.
   A bar in the current card shows how long until the next step; hovering the cards pauses, clicking one jumps there.
   Everything that moves is transform or opacity, so it stays smooth. */
