Wallet hub rows on bank, exchange, and merchant landings used vague mono icons that were hard to tell apart. Replace them with multi-colour brand-style marks for Chrome, Firefox, Edge, and Brave. Hub label becomes “Web browsers (experimental)”. Also drop the circled “①” prefix from the shop pay popup “Wallet payment” label — leftover copy-paste artefact from an earlier draft, not intentional numbering.
