   Homepage, after the four job cards:
   1. "Why believe CarbonAI", one section in two acts (.arc):
      Act 1, scale: slowed forest canopy footage under a teal-slate overlay,
      with the four metrics counting in. Typography carries it: no
      per-metric graphics. A long fade to white leads into Act 2.
      Act 2, trust: four selectable differentiators beside a large
      evidence panel that demonstrates each one (carbonAI/js/arc.js).
   2. The final call to action.
   Headings share the scale of "From research to decarbonization
   decisions" (jobs.css).
