A sky-circuit strung through the weather. Every lap you finish opens the next TIER — the whole field gets 13% faster and the grip does not keep up, so corners that were flat on lap one need the airbrake by lap three. Boost is not a key you hold: you earn it off the light-strips, out of a rival's slipstream, by carrying a corner on the limit and by grazing the barrier without touching it. Everyone antes $3030 and stakes cards into one pot; a small rake burns and the podium (1st/2nd/3rd) splits the rest.
