/* RazorCX: a loading dock. Concrete ground, paper manifests, and five gate panels stacked like dock doors with container ribs on top.
   On desktop a manifest strip stays in view beside the ladder and slides to the gate the reader has reached; on a phone the gates stack
   and each one carries its own manifest line. Tier colours are the only accents and mean what the gate says. */
