A small but real-feeling app that uses every AjaxSlim element together. Edit it like real software: pick products, change quantities, add/remove lines, save. The grand total is the canary - it sums values you edit through several different elements at once, so almost any cross-element glitch makes it visibly wrong. (Integration scenario - the whole point is that the parts work together.)
