Bind · the counter
Fuel is prepaid time. It works like a transit pass: you load it here, then the ride does not stop to count change at every stop. Unused time stays on your card. This is not a share of the company and not a coin.
Each box opens Stripe for that exact pack. You leave this page, pay there, and come back. If you would rather send a gift with no ticket back, that is Donate — bank or crypto, no card.
If the meter hits zero mid-ride, Iris will say we need more Fuel if you want to go further. She will not turn into a robot while you top up. Bank transfer or crypto with no card lives on Donate.
