  zeronatural.studio is registered at the head office; its DNS runs through the
  head office or the 6th branch. The .net and .org registrations are kept
  inside Cloudflare end to end. The .dev was taken at Spaceship, which the 3rd
  branch already works with, because it is the one most likely to be used.

  The four held domains sit with separate groups deliberately. Nothing else is
  ours.

/* CREDITS */

  0 through 2.5
    One credit, USD 50,000. Sold in tens above a hundred. Every run cost a
    whole credit at minimum, whatever it was.

  3 onward
    The price of a credit fell sharply. Sold in twenties. A run costs between
    a tenth of a credit and one, by what it asks for.

  Ion runs on an earlier generation. Which of the models between 2.5 and 3.1
  it draws on is not published.

  Above the lightweight tiers there are two models. They differ in total MoE
  parameter count.

  Nova is still billed in credits, at 250,000 output tokens to one credit.
  Neither its pricing nor its operation resembles the tiers above it.
