Below, an area bar: All city / East / West / South, defaulting to \"All city\".\n\nThe main body is a merchant list, 22 in total: East 8, West 7, South 7. Each needs a shop name, area, rating, per-person price, and a \"Favorite\" button. Ratings start at 4.9 and decrease by 0.1 per shop, and once they reach a minimum of 2.8 they cycle back to 4.9. Per-person price is computed by position: the n-th shop = 30 + n × 5. The list defaults to rating high to low." |
