   AirOps concept 04 — "Switchboard"
   Saturated ultramarine field with a chartreuse accent. Where the other
   concepts lead with copy and cards, this one leads with an interactive
   scenario board: pick the call, watch the shop handle it.
   Behaviour comes from the shared /concepts/concepts.js.
