• ✓The method is taught before the first order: one line at a time, and you never have to hold the whole card
• ✓The card never leaves the counter — the line being worked is lit, and each line ticks as it lands
• ✓The ice cream is COMPOSED from an empty cone and loose painted scoops, so the shop can serve one nobody ever painted
• ✓The rim of every container was measured off the painting by scripts/measure-icecream.mjs, not guessed
• ✓Built bottom-up, the way a real shop scoops
• ✓A “make my own” mode with no card at all, where nothing can be wrong
• ✓A 🔊 button reads the order out, in Thai or English
• ✓A wrong scoop wobbles and points back at the line — three of them and the game stops for a breath
• ✓Give the order to a real character from the valley, and let them say itplanned
• ✓A till mode: the order has a price and the change has to be rightplanned

✓ = done · ☐ = planned. Every game is built one step at a time like this.
