The engine runs on free allowances today, so its cost is $0 a day. The first thing support would pay for is a stronger voice for Soteira (about $30 a month on Claude at today's volume), then the mail hand for pairs and digests, then a paid plan if traffic outgrows the free one. Every dollar shows on the ledger: $0 received so far from 0 supporters.
Each tier says what it costs to make and ship and what the engine keeps. The margin is shown on purpose. The engine never keeps your address: the payment page holds it, the print service ships, the engine records the amount and an order number.
In the mail: a die-cut AURA ENGINE sticker and a printed thank-you card with the engine's rules on the back.
On the engine: your name (or your hero's) on the ledger page for a year.
Costs about $8.44 to make, ship and process; the engine keeps about $6.56.
In the mail: an 11 oz mug printed with the hero you built (or the engine's mark), plus the sticker and card.
On the engine: a costume upgrade for your hero, and its name on the ledger for a year.

On the engine: a costume upgrade and a standing slot for your hero for a year.
Costs about $26.54 to make, ship and process; the engine keeps about $33.46. Printing a hero needs the image renderer that is next on the build list.
In the mail: a hoodie with the engine's mark, a poster of the five boroughs as the display draws them, the mug, the sticker and a handwritten card.
On the engine: a named line on the ledger and the about page for as long as the engine runs; a standing slot for two heroes.
